SEQ MIDI-->CV Routing Gatelength issues

Quick question.  I'm trying to use my Midibox SEQ3 as a MIDI-->CV converter to play my Ableton Midi sequences.  This works great for the relevant CV out, routing via the Midi menu -- except Gatelength does not translate appropriately, no matter what I do.  Has anyone else noticed any similar issues?  When I start the pattern, it appears that the AOUT Gate out turns on and just stays on.  My AOUT CV & Gate outs work perfectly when driven by a SEQ track, so I'm guessing it's a firmware issue (or something I'm missing that may be turned on or off.)

I've been considering building a second core and making a Midibox CV to replace the AOUTs of my SEQ, to rectify the problem.  But I'd rather not.

Please let me know if you have ideas!  I've been working with the sequencer heavily.  Attached is a pic of my modular console, with Midibox SEQ on the bottom left (i took it out of its desktop console -- and really want to redo the panel soon.)

Thanks,

Lars

Wow, gear porn! :) Do you allow me to blog this picture?

I looked into the code, and it seems that Note Off won't be handled correctly (only Note On with velocity 00, as this is what MBSEQ uses internally). A bugfix was easy, but I'm currently not able to try this out by myself...

So, could you please check if the modification is working?

Wow, gear porn! Smiley Do you allow me to blog this picture?

Absolutely!  You don't have to ask. :)

The trigger pulse outs of the SEQ are hardwired to all the trigger inputs of my modules (drum modules and envelopes) from behind the panels -- this way I don't have to patch them.  (The 6 modules on the left side are cloned 808 voices and other drum circuits.)  You can see there is an "AOUT" module with the 16 jacks for CV/Gate outs.  The back of the synth has an auxillary panel with the 2 MIDI ins and 4 MIDI outs from the SEQ.  There are also two Footswitch inputs, for seq start/stop.  I use it mainly to sequence analogue gear, the MIDI data is sent to sync our video projection software, etc.  The Midibox SEQ is the core part of my rig and I'm in love with it. :)  I want to build a new panel soon, with the 64 LEDs, and maybe a second MB808 seq too.  I also am going to make a dedicated tempo display/BPM encoder.

Thanks so much for checking this out for me -- I will drag my rig into the house tomorrow and try it out to see what's going on.  :)  I'm going to be Nine Inch Nails at an early 90's cover band show this Halloween, and I am doing it the lazy way by just downloading midi files. And playing them thru the SEQ-->AOUT via a laptop. :)

I love the fact that amongst it all, you've got a Mirage tucked away up there..

Maybe I like Skinny Puppy too much... haha.  I just bought a Drumulator too.  :)  The Mirage is great...

Hi TK --

I tried to compile the src files from the zip file you posted, but am getting a bunch of errors (several thousand.)  I'm using MPASM the same way I have used it to compile the source files after modifying the configuration file before.  Am I doing something wrong?  I can't use the default hex build because my buttons are configured on different pins.

Thanks,

Lars
