hapaxOs 1.12 - new firmware

Hey y’all !

This is it, 1.12 is here !

It’s mostly bug fixes, but a couple of new features nonetheless, like 14 bit CC, key tracking, envelope sidechaining, and more.

A big thanks for adding support for 14-bit CC values! :tada:


Nice, Velocity now available in the Automation list!


Can Sidechain be triggered from other tracks?

The ability to shape and tune arbitrary envelopes over CV is mind blowing! It satisfies the function of a >$100 module in a single FX slot. :clap::clap:

What’s the intended behavior of selecting the ‘sidechain’ parameter? Inverting the envelope?

I don’t see any differences on my oscilloscope when sidechain is on or off.

Figured it out thanks to the excellent manual. Curve A, Curve D and Depth all need to be negative. Then tune curves to taste! Thanks Squarp team!


Nice. Spotted one of mine is the new features list (FILL as a source) so thank for that especially!

Thanks for y’all’ feedback, I spent a lot of time optimizing file I/O, and it’s gratifying to know it’s appreciated :sweat_smile:

Really still hoping for midi import and few extra midi fx though and consolidation of midi fx on tracks

I LOVE how fast it is. I no longer have to anticipate ahead of time loading up the next track. It’s fantastic!

That’s exactly what I’m trying to do right now and I can’t figure it out. I made a post about it. Hoping someone knows what’s up!
