MIDI OCTAVIUS - A MIDI Transpose module for synthesizers and other devices

video upload by MIDERA

"Hello! I have developed my own MIDI transpose module.

What does it do?
It takes the MIDI note date in from your respective synthesizer to your sequencer (or even back into the synthesizer to play back the note data) and transposes the note data up to two octaves up or down. You can select your own MIDI Channel by long-pressing a different MIDI input channel.

Why did I make this?
I became frustrated that a company wouldn't implement a MIDI transpose mechanism for their synthesizer, thought they'd add all sorts of other features. This has been in development since January of 2026, or something like that.

Who is this for?
Anyone who has a synthesizer that they want as their master controller, but it doesn't have MIDI transposition buttons.

Prophet 10 and MIDI MORPHEUS - an LFO generator for the Prophet 10

"When I was playing around with the Roland MKS-80, I kept thinking "My Prophet 10 sounds soooo much like this, do I really need to spend $$$ on getting an MKS?" The things I loved so much about the MKS (and actually the Kawai SX-240 which I sold) related to the LFO. I love a good reverse saw LFO and a random LFO. Notably, these are absent from the Prophet 10.

I started building another device I haven't showcased yet, and I realized I could repurpose that work to make an LFO module, which is what you're seeing here. So what can it do? It currently targets multiple CC destinations with adjustable depth, speed, and waveform shape.

Been having a lot of fun with it so far, creating sounds the Prophet 10 could not do unless I had a Yorick LFE, which is no longer made and was a little too expensive for me to justify purchasing. This is far cheaper (although I don't want to think about how much I've spent in parts/time building this!).
