Thank you for your message. My english is quite limited ... i will do my best. in fact it is not only a question of transposition. Basically, when I connect a controller (bsp or keystep) cv gate to rings (cv to v / oct and gate to strum), I can only play the notes on a very limited part of the keyboard. Afterwards, no matter which note I ask it to play, it remains stuck on the same note (the last lowest note or the last highest note). We can hear it in the video. I can't go down or up in octaves, can't use the transpose function. No problem with my controllers and other VCOs. This is a DIY module that I bought used and I'm starting to think whoever sold it to me wasn't being honest.

Ask me if you need more details.

Thanks !
