  1. ALPS Motorfader for sale

    Hey, I want to get rid of these. They worked fine when I removed them from my build some years ago. Since then they were stored in a locker.  Since I have no chance to test them I'll sell them as non working (although I'm pretty sure they work well).  I'm asking 15€/pc for the CP K Fader (I have 6 in total) and 45€ for the bulk in silver.  Those prices are just an orientation. If you are interested, drop me PM and we will see. I really don't need them anymore.  Best, Chris
  2. Fatar TP/40L Midification

    Hi Andreas, if you use the NG-App for this task, you will end up with a quite bad velocity resolution. You only will get about 16 different velocity values or so instead of 127. This is due to the lower scan rate. If you want the full resolution, you'd need to take KB.
  3. Need help for building a MIDI keyboard..

    If you are up for the best performance and you don't want to dig into code: use both with two separate Cores. KB can't really handle LCD displays, pots und push buttons. On the other hand NG is not optimized for keyboard-scanning. The scanrate is a a lot (!) slower. And you will get a very low velocity resolution. Maybe 20 values out of 127 or so.

  5. Help needed with MF_NG

    It works great with the correct PIC18F452 ;-)
  6. Help needed with MF_NG

    Thanks! I'll order a 452 and try again... Thanks, Chris
  7. Help needed with MF_NG

    I've just noticed, I've used the PIC18F4520 instead of PIC18F452. Could that be the problem?

    $12 only if you want me to do the SMD assembly. If you do it by yourself it's $8 + $1 for soldering-parts and $5 for elastomer. ;-)

    You only need a few 10k 0805 resistors, 2x 74HC165 in SMD and 100n 0805 filter cap. That's it. If you want you can add a 10u 3216 Tantal-Cap to the input of the LEDs. There is a footprint for it. So all in all less than $1 or so for parts for 1 module. 
  14. Help needed with MF_NG

    Hey people, I have a problem  and I hope you can help me. I've created a PCB based on MF_NG. Schematic and layout see here: I have a PicKit3 to program the 18F4520. I use the MBLAP X to flash the bootstrap to the PIC. The programming seems to work fine. I don't get any error messages.  As stated on the MIOS Troubleshooting page there seems to be a problem with the ID when working with MBLAP. See here (bottom): So I also flashed the bootstrap-workaround which also ran fine. If I now connect the MF_NG via MIDI to a core, I get this error message:   [395386.494] [MIOS32_MIDI_Receive_Handler] Timeout on port 0x20 Do you know what that could cause?! Best, Chris
