Re: 9700 MIDI2CV8 acting strangely - note scale wrong

Hi Scott Thanks for the suggestions. I tried reseating the firmware chip first as the easiest option after a quick visual inspection of my quality soldering job, but still no go. So I reflowed all the solder joints on IC7 and IC8 and it is working again. Clearly my soldering job was not quite the qu...

Re: 9700 MIDI2CV8 acting strangely - note scale wrong

I gave this some further thought, and starting with C=0 instead of 1, then converting the numbers to binary, any 'bit 2' is being ignored.

In Out
0 0
1 1
2 0
3 1
4 4
5 5
6 4
7 5
8 8
9 9
10 8
11 9

So maybe bit 2 of DAC output is misbehaving?

9700 MIDI2CV8 acting strangely - note scale wrong

Hi Scott I powered up the 9700s today and found that the note intervals are 'messed up'. It has worked since build in mid 2010, and I have made no mods, or changes. If I play a C, then C#, I get a semitone interval, but then D sounds a C again. Arbitrarily calling C 1, C# 2, D 3, etc to B 12 I get t...

Re: Newbie from Belgium with a problem...

Hi Scott

Thanks for confirming that. It makes it easier than having to maintain separate 12 and 15 volt supplies for my MFOS modules and teh extra Paia modules I would like to add.

Re: Newbie from Belgium with a problem...

Hi Scott

Is this also possible with the new 9700 modules? Do they have the regulators already soldered? If so, can you just bypass them?

Thanks, Peter

Re: What would be cool new 9700 modules?

Hi Brian

I would love to see a voltage quantizer. Having the option to select from different scales would make it more flexible, but probably require an MCU which would have a longer development time. So, a simple 12 tone unit would be great.

Built my 9700S

My first modular, and first electronics kit in at least 15 years... I received my 9700S kit about two weeks ago. The final screws went into the frac case eight days later. I had two issues, both traced to dry solder joints, otherwise it went together well. Wiring the PCBs to the front panels was ted...
