USB Midi behaves differently in VCV rack vs MetaModule

  1. Patches played in the metamodule hardware are two or three octaves higher for me than the same patch played in VCV rack. I tried this with both an Arturia Keystep and an ASM Hydrasynth via USB midi, with VCV rack running on an Apple silicon MacBook, using the VCV Midi->CV module v/oct jack straight into any oscillator’s pitch jack.
  2. On a monophonic patch, VCV rack’s Midi->CV with a VCV VCA module will keep the gate open as long as I have a key held down. For example, when I hold down an A key, then press another key B while still holding down A, and then release key B, in VCV rack, note A will still play. In the metamodule, doing the same thing with the same patch will terminate note A (The gate is closed, A will not play again until I release it and press it down again.)

Are these limitations of the Metamodule Midi to CV implementation, or are there some settings I am not seeing? Or should I be using a different module? I would really like my patches to respond to midi the same in VCV rack as in the hardware module.

Thanks!

i noticed also about the octaves higher issue

Thanks for the detailed reports.

  1. I’ll check this out. There shouldn’t be a difference between using MIDI in VCV vs. on MM, but I’ll see if I can reproduce that. IIRC there are at least two “standards” for MIDI Note middle C is, so maybe VCV and MM are using different standards (though, odd I never noticed that before).

  2. OK, I might know why this is. The MM has an algorithm for this type of thing (more notes pressed than the polyphony#). I’ll bet VCV’s way of handling that is different than MM.

Ok the MIDI pitch difference was fixed in firmware v1.2.0 (releasing it now…)
