Glad you got it to work :)

Koshi: I'd guess you have a problem with the CAN bus parts. (Diode + Resistor), cause they typically cause random rebooting etc. when missing/wrong. This would also explain, why it only happens with the mbSID firmware. Make sure you have R16 and D3 (orientation!) mounted (correctly). They're right above the PIC. Also make sure there's no jumper or the likes on the CAN header.

7.5VAC sounds good for a 7805. That'll be roughly 9.2VDC before the rectifier.

Seems to work here.

Now that's timing - I am just implementing exactly that :thumbsup:;)

You can use this test app: But. I am pretty sure it won't help you, since you have a bigger problem. Your CS pcb is doing really weird things. 1) Remove the CS pcb. 2) Find the shorts that you most likely have on it (big blobs of solder, bad soldering, ...) 3) Make sure all the components are in the right place and correctly aligned (ICs, diodes) 4) If all that checks out put it back together, remove the ICs on the CS pcb and measure the voltages on all ICs on the CS pcb. 5) Report back.

True. Thing is - you are not the only one having to make that choice ;) If 60 people decide to ask, that's one hour of work for me (and 1 minute is pretty optimistic here, as an answer takes longer 98% of the time). You seem like you've done your homework though, so it's all good. Back to topic: Is some transport buttons really all you want?

Thanks, fixed.

If all you want is some (<8) transport controls, a core module is all you'll need, as you can use J5 for 8 digital inputs. Typically - if you have some C skills - writing a custom app from scratch will be faster than digging through the partially pretty big applications to find what you need. Since MIOS handles pretty much everything for you, it's only a matter of finding out what MIDI events to send and sending those when the appropriate button was pressed.

DIY! :) Prolly the best thing to do, if you want a one big custom board anyways.

Welcome abord, Razer :flowers: Let me guess - you have spent countless hours searching already, but somehow managed to not stumble across http://www.ucapps.de, right?

Search for the term first then :thumbsup:

22k/10k are good. That's really not helpful. What doesn't work, how do you know it doesn't work, show a schem, some photos, something. Like I said before, that opamp will not solve the problem.

If ASID XP plays it properly then my version will play it properly as well, if you set the flush mode to ASID XP ;)

PBE is a reliable seller, they do have hace a min. order of 50eur though, so it's best to get 2 or join forces :)

Not quite. 6VAC is pushing it, admittedly. 9VAC is already a bit too much. 7VAC is perfect. That good explanation says Vdc = Vac * sqrt(2) - 1.4V, and not as you quoted Vdc = (Vac - 1.4V) * sqrt(2). Hence for 6Vac you'd get 7.084Vdc ;)

Those are the relevant pins for you. It does need power. Vcc- needs to be tied to ground and Vcc+ needs to be tied to +5V. Unless I am completely blind, that's not a rail-to-rail opamp. The circuit will still "work" but not improve the situation at all, since the voltage will be clipped @ roughly 1V and 4V. You want something like an OPA347.

Gain = 1 + R2 / R1

Correct :) Solder some random led-blinker kits or sth and you're good to go. Keep in mind - the stm32 comes pre-soldered, so all you have to do is diy-friendly through-hole stuff.

SVN is not read-only. If you're only toying with some apps, you DO NOT want to commit (= write back to the repository). The /!\ tells you that the file has been changed locally and is not in sync with the repository. That's okay. Don't worry about it. You do not need to upload your code to test/run it.

Hiya MrTorsionTorque, what you can do is to basically just use the touch-sensor part of the motorfader design on ucapps. Reference: http://ucapps.de/mbhp/mbhp_din_touchsensors.pdf To power the whole thing via USB and have USB midi, you'd want to use a core32 module. For the 32 keys you'll need one DINx4, and another DINx1 for the encoder and the two buttons.
