Video's still going strong! Just got a Fostex X-12 and successfully modded it using your instructions! Thanks a million this thing just got so much better!
awesome! Hey, as I've learned, the fostex operate best with endless loop tapes that are professionally made. For some reason, mine often have problems with the splices in the endless loop tapes that I make myself, so I just run some of the professionally made ones instead and they usually don't get stuck. I don't know why the fostex have this problem, my tascam never does. Just a useful tip I hope. good luck with your new build!
I did this to my fostex this morning. I had no idea how easy it was. I used a pot from an old cob radio. Thanks for posting these videos
Very good
So, i did the mod yesterday. Tried with a 1K Potentiometer and it was really too fast. So I tried with a 500K, and it worked well. The Wirering is good : 1st red cable on A, 2nd red cable on B and 3rd black cable as the ground connected to metal frame. I hope this can help some of you. Cheers.
I love this video! This was a pretty simple mod to do. The hardest part was getting the wiring to fit beccause I added a bypass switch. I was SUPER afraid of bricking the machine because they've gotten really overpriced in the past few years.
Thanks for the tutorial! Finished this today with a crappy soldering iron (not recommended) and a 500K Ohm potentiometer. It’s not a linear potentiometer like advised, but I’m able to go faster and slower, allowing a ‘normal’ speed. The pitch/speed doesn’t change much in the middle of the potentiometer. Only when you go to the edges.
yeah that makes sense with a logorithmic or exponential pot.
Hey man I have a Fostex x-14...mod worked like a charm! Thanks buddy...
Sorry I never saw this comment, I'm so happy it helped you!!! yay.
@Luca Pritchett Can you make a guide for that becuase i have one and i would like to attempt that mod
@@oscar909500 I think he just followed this basic tutorial. they all work the same basically and this tutorial should work with the x14
I followed your tutorial and it's great, and I've added a switch to take it out of pitch control mode. My problem is thatI've found that bending the earth wire connection near the pot is making the motor run at very high speed. Disconnecting the earth makes it run at the speeds I want. Is the pot perhaps faulty, or would it be OK to just earth the lug to the pot case? Sorry if that sounds confused or nooby, but any help would be gratefully appreciated.
This tutorial was confusing at some points but everything worked in the end. The little screw that controls speed was broken off but it was on the right tempo anyways so pretty dope!
This is the most beautiful track I've ever heard being made on a Lyra 8! Is it only the Lyra? Respect!
Thank you sir! That's the Lyra 8 and Bastl instruments Micro Granny going into some reverb! mostly the Lyra, but the Microgranny was providing some steady drones :D
I enjoyed the vid, but I enjoyed the your track even more bro, the Lyra-8 sounds amazing, great job
Thanks a lot! I appreciate it :D
User 173 do you publish your tracks? Maybe SoundCloud or spotify?
@@rafaeltrabolsi I'm really new to all this, so not as of yet. But I am currently working on my first album, and hope to release in july/ august :D
User 173 Cool, I’m prepping for release as well. Let me know when u do, I’d love to listen.
@@rafaeltrabolsi I'll be sure to check yours out. Let me head over to your channel now to subscribe :D
"This motor is perfect as is, just like you."
:) aw
just ordered one of these. definitely planning on adding this mod when it arrives. ever do the same thing for the casio sk-1? i have one i've been wanting to modify with a simple pitch adjust knob but have no clue where to start but a video like this would help big time
Hey, funny you should ask, I'm starting my SK-1 video in the next week or so. should have a full circuit bending tutorial for ya soon!
nice work !!
cheers man
Nice work ! I will add to mine !
Please anyone know how to fix the problem with pause button ?? The little white piece that let holds the button is missing , I have got a x-55 and it looks the same but this one the white piece was broken
This is so cool! Do you know if there's a way to slow down the fostex x-18h? I would love to see a vid tutorial about that!
Great tutorial. I'm looking to modify my Fostex X18 (which already has a pitch control), but ther range is too small. I'm wanting it to go from very slow to double or 3x speed. And I"m also hoping to be able to play in reverse, will this play the music backwards or does this just play the other side?
Hi, thanks for putting together an amazing tutorial! Sorry for a noob question, this is first time modding a gear for me, but when I connect the potentiometer the default pitch becomes very low, even the knob is turned all the way up. I tried re-solder a few times because my soldering isn’t very well, but it did not solve the problem. Cables are connected the same way you did, and the potentiometer is 1k ohm. Is there anything else that I should check to see if I’m doing something wrong? Thank you so much!
Same
I switched to a higher resistance pot (ended up with 20k) this made it go from even slower to a bit faster than normal.
@@beyshore_ Thanks for letting me know! As long as I have both normal and slower speed I can live with that. I’ll give it a try!
@@beyshore_ legendary, was having the same issue thanks so much for the tip!
Hi there. I’m actually trying right now to do the pitch control on my foster x12. I am trying to figure out where on the motor and the pot you are connecting the wires. To get it that slow. I am getting it super fast. And a little slower. Just not that super slow you are getting:(
Same here! Any luck with this in the end?
are you using the right parts? You're adjusting the variable resistor on the board? if it's acting funky, it could be a bad solder on the main pot or most likely a ground that's not connected properly.
Nice mod!
Not sure if I have the precision tools to get this done.
they are all fairly cheap. you can get em on amazon.
Hey I'm a bit afraid of doing this , but it doesn't seems so difficult, i just don't understand what you mean by Fine tunes at 6:24 , it's this to get the right amount of slow on the left and the fast on the right, because you can also have something very very slow even if your turn on the right? depens on how you fine the tune? i don't know if i'm clear
I bought one of these units around 2004-05 ~ish. Nice little unit to record on. I think I lost it, either that, or my mom gave it away :/
Sorry to hear that man, that's awful. I hope you find it still.
Thanks for this. About to attempt a speed mod for Tascam MFP01. Hoping to be able to use both a pitch pot, and a cv input using a cheap vactrol. Wish me luck.
Unfortunately it did not work for me. I used a 1k linear pot and connected everything the way you did, using a screenshot at 8:19 for reference. The speed ranged from normal to super fast, but not slower than normal speed. Also tried different conections but that didn't work either. Bought the X-12 a few days ago planning to do the mod, so I'm a liitle disappointed right now. Maybe you have an idea?
So, i did the mod yesterday. Tried with a 1K Potentiometer and it was really too fast. So I tried with a 500K, and it worked well. The Wirering is good : 1st red cable on A, 2nd red cable on B and 3rd black cable as the ground connected to metal frame. I hope this can help. Cheers.
@@somethingintheuniverse760 Thank you so much! I'll give it another try! Just have to get a 500k pot. Hope it'll work! :-)
Keep me informed !
Love these, super helpful, thank you! I've got an X-18 I'd love to make slower, would this mod or a variation work on models that already have a pitch adjustment? Also, does it let you pitch up, or just down?
If it already has a pitch adjustment, then you are in luck and need not do anything! and my mods do pitch up and down, fo sho.
@@User173 awesome, yeah i wanna go reaaaaaal slow, and it seems like these don't drop down that much, but seems like I could wire my own thing in parallel and go pretty slow indeed
@@mrquint15 you don't have to go that far. follow my beginning part of the tutorial, and you can just install the pot, keep the old motor, and it will come to a complete stop at full turn. so you could go massively slow. *edit sorry, follow the beginning part to my TASCAM pitch control video and do that version. just install a pot going to the power and ground of the motor, not the pitch control board.
That’s the best machine ever
I quite like it! Although I love the Tascam 414 too
@@User173 The Fostex X-12 was my first 4 track. I am scared to do this mod even with your video. I will probably upload into digital program to clean things up and then record on a fresh tape in my Sony TCM200 and go out of that into a mixer back into the four track and just repeat the layering. Only using digital for four tracks of compression at a time. Its longer but I like the process. I really like what you did here but unless your my buddy and in my garage, I will avoid this. Just because these are becoming more rare and i dont trust myself with modifications or repairs. Are you in the states? Want to do a project together?
@@dylanlarson435 I am in the states. what project do you have in mind? I understand your trepidation, I really do, but I swear it's not really that hard and almost fool-proof. but, you do you, I'm just happy you watched and took the time to comment. thank you!
@@User173 I could email you some files or upload somewhere. Here is one of my projects soundcloud.com/goony-bird
Would be possible to attach separate audio outputs in it?
Great videos!
I currently have one of these X-12 machines and would love to get a pitch control on it. Do you offer services for installing one of these on my X-12? Thanks!
Hey, unfortunately I do not. I'm not a professional musician or tech, my day job is as a concept artist and I do a lot of extra freelance on top of that so I'm so busy I couldn't promise to complete it any time soon. But I'll gladly walk you through it and answer any questions you might have!
what type of pot did you add to it (500 ohm or 1k linear?) - it looks great! I'm gonna try and pick one of these bad boys up tomorrow
Good question, I guess you'd have to have seen my Tascam video to know... I should have thought of that. I used a 500 ohm Linear pot m'man.
@@User173 oh my bad you actually explicitly say at 6:30 (ish) that you're using a 1k pot. I just want to point out that I tried this mod today with the X-12, and it appears to only increase the motor speed when the pot is grounded. On the motor there are 4 terminals (A, B, +, - ) and after adding an un-grounded potentiometer between A and B the base speed decreases significantly, which allows some control in pitching up to near "standard" speed but as soon as the pot is grounded the speed jumps significantly. On a B1k resistor, with the third pin on chassis ground as you suggested, the resistance control is from 0 ohm (standard speed) to 1k (very fast). I tested with a variety of linear pots to the same effect.
@@theotherson that is the correct way to wire it. Please see my in depth tutorial on this mod for the tascam and the schematic I showed at 28:01 on that video ua-cam.com/video/r09fyeutzvc/v-deo.html as that is the correct way to wire it. I'm stoked you have it working!
I was able to mod my X12 to go from stop to about 3x normal speed.
This is great, looking for an X-12 now.....
What happens if you use a bigger pot? like a 10k or 100k? and what happens with log as opposed to lin pots?
I believe that the motor will only respond to a certain amount of resistance. large enough, it will just shut down the motor. but the Motor won't spin any faster than it's max RPM listed. The audio pots are exponential, and therefore will have more power near the outer edges of it's range. so the middle range will barely change the pitch/ speed at all, but instead only the full clockwise or full counterclockwise ranges will see the most effect. For this, you def want a linear pot.
User 173 ah ok! I have a 100k it seems. I'd guess that'll be ridiculous. I'll order a 1k for when the tape player arrives.
Would it break the motor? Or damage anything? I'd be curious but i don't want to test if it's a risk.
Thank you so much for replying and your channel is great. Actual in depth tutorials on this stuff is a real find. I tried tape loops a few years ago and just got so disillusioned with it, but going to have another crack following along.
@@ggb1169 Glad you're finding my channel useful! I'm planning more tape tutorials soon. just need to get the time... these videos are actually a LOT of work. haha. I don't know if it'd break the motor, I seriously doubt it. You can easily try it and see, but no, it won't break the motor. However I don't think that stopping the motor all the way and doing so for a long period of time would be good. just try it and see, if it's no good, then re solder in a 1k :D
User 173 ok great! I'll pluck up the courage and give it a shot. I'll let you know what happens.
Through mine and friends limited experience it sure does take a lot more effort than most realise, so I'll be following keenly.
Any ideas for making various length tape loops would be great ;-)
@@ggb1169 Yeah that's something I've been considering heavily. However I've come to realize that the professional companies that make endless loop tapes do it at a much cheaper rate than it would cost to go beyond the 5 and 10 second loops that I show in my tutorial. In fact, the fostex x12's tend to have a problem with the splice points getting stuck sometimes and it's very frustrating. in the end, I'm just using my very best spliced tape loops or online purchased for longer loops, like 25 seconds.
I did take apart the message machine tape loops and discovered that you need special cases to make the longer loops. so again, that's why it's just easier to purchase the longer one's online :D
Does that ground wire come with the Kalevel connectors?
yes
@User 173
Can you make a tutorial on the Fostex x-14
yes, let me see if I can pick one up for a decent price. But looking at the x14 just now, it's the same parts. you can just follow this tutorial and it will work.
@@User173 thank you, i think you can get one for like 90 dollars american
I see that your motor has four soldering points: A, B, plus and minus, according to other photos I've seen. And you're soldering the pot to A and B, I guess. The motor in my X-30 only has two soldering points, lacking the A and B. I guess soldering a pot to plus and minus will only create a short circuit.
the motor I'm using is from a previous video about doing the pitch control to the Tascam. I explain it more there, but it's a speed control board. you have to buy that motor and replace yours. However, in my previous video I show a way to pitch control with the motor you are using. Watch the tascam pitch control video, it will show you all you need to know :D
Would this mod work the same on the X-15 as well? Thanks.
love the Fez Icon. I still listen to that soundtrack nearly every day. haha. Yeah I don't see why it wouldn't work. The only thing is you'll have to open it up, inspect the motor and see if it's a variable speed motor already or not. you'll also have to do your own inspection into where to fit and drill the pot. but it should be the same or similar process for any four track recorder.
User 173 disasterpeace is amazing. I like his hyper light drifter sound track. Also “it follows”. My other favorite artist is cristobal tapia de veer.
Thanks. Might try getting a portastudio 02 if I can do this mod on that as well. So just look for variable speed motor?
Can you connect it to a laptop using an interface if so what cable to use
Do you know if adding a momentary switch fro disable the erase head is possible on these?
yes, totally. I was going to do it to mine. maybe I should shoot a video? would that help?
@@User173 that would be awesome
@@User173 Did you get around to doing this?
