I found three bugs in V1.2 (they might been there in previous versions too) .... 176 98 86 176 99 0 should select the arp rate, also not happening. Fixed this bug! I can make it operate in multiple ways though. What would be the preferable operation? 1) Sending ARP Rate NRPN only changes the rate a...

Hello all, I've put up my modified OS on Reverb for those of you who need actual ROM chips. You can send DM and we can work out a price for just the files if you can burn your own. Still working on the code, so I will keep you all updated. Found the Arpeggiator key sync code too so that will be a se...

Been looking at these issues the past few days. Good find on the Split Point/Arp Rate bug... it is in every version of the OS. Still trying to figure out why this is happening... Testing the joystick on all OS versions seems to work as it should when no Mix Modulation is going on... if I move it to ...

More updates on r1.3 ... or maybe it should be r1.4 now. Changes from r1.2 in bold . 1. NV PROGRAM NUMBER: Program Number is now remembered after power off 2. DATA INC/DEC: Data increment/decrement function has been added for fine adjustment 3. LFO SYNC : By default the unit has freerunning LFOs. If...

As it stands I am using empty space at the very end of the eprom for my code. Figured out most of the panel switch addressing, then cod...

I've recently begun working on the 68k assembly for the VS and the first thing I did was disable the LFO reset code in v1.2. Eventually when I figure out the memory & button mapping I will make it selectable. Among other things, I also want to fix the NRPN byte order problem so that any controllers ...

Does it power on at all and show patch names on the screen?

The VCF chips should be in sockets. Determine which voice is acting up and swap filter chips with the next one. If the new voice is slow, then chances are the chip has become temperature sensitive. Let it warm up, or get a new one. If all voices sudenly are OK, the sockets are dirty and/or corroded...

That is definitely a PPG Wave bass. I remember reading something where that is mentioned, but I also have a close if not identical sound programmed into my PPG Wave 2.2. The Wave is currently living in a studio right now while I record, but next time I'm around I'll get the patch information and see...
