RJModules (v0.5.0): voltages aren't compliant! #24

Open DomiKamu opened 6 years ago

DomiKamu commented 6 years ago

Hi,

I report you an issue about non-compliant voltages on outputs of some modules I've tested (Supersaw and BPM): these voltages are too high/over limits, regardling Eurorack Voltage Standards document, here:

This is applicable, for example, for Supersaw module: output is 0 to... around +22 V (when MIX knob is set at max - default - position).

Also, BPM should sends +10V, not +12V.

I don't have tested other modules yet, however.

Regards.

+1, Supersaw is definitely blown out. I didn't know what I was doing yet. Thanks for the report.

You're welcome! of course about Supersaw the "culprit" is the "OFFSET" switch (when on - default position). In case you'll plan updates (and only in this case) the best way, in my opinion, is to disable the OFFSET feature (always turned) off, by this way, voltages stay into -12 V ~+12 V range.

I'll study the source code ASAP.

Hi (long time ago - 1 yr and half) I've seen you've started your plugin migration to Rack v1. For personal usage only, I've ported "Button" and "Buttons" only (custom RJModules plugin), so be careful, as indicated in VCV Rack Voltages, output voltages must stay in -11.7V ~ +11.7 V bounds. Best is +/- 10V. For now, both Button and Buttons modules send +12 V.

Regards. ;)

Hey Domi, you want to send a PR? Are you actually sending those values to real devices or something? I'm not sure why it really matters 11.7 vs 12 in a digital space, but I'm happy to accept any pull requests for your needs, I just don't get why it matters that much. :) But ok!
