So you are the Mastermind behind the sequencer? yay! I just lost myself in…
it looks vaguely similar to Jeannie Sequencer, take a look at it:
Rolf is a genius! He’s now working on a new sampler with a new poly sequencer also.
Myabe you can get one or two inspirations from his work at sequencer.de!
I tried to read all this thread but it’s 4 years long!!! wowwowowow…
I will give you my two cents feedback…
I have created a 8x8 matrix sequencer, then loaded for each scene an audio sound, put into synced loop, and some stuff happened…
1 file of the first scene preset name got repeated to all columns below
2: I tried making the bars for one scene as long as possible because I wanted to try to load an entire song, but 64 bars weren’t enough. Tried play one shoot all loop but it didn’t work either.
Would be cool to have a play full sample, synced and not synced also. Like a double deck Mixxx Dj console basically, with a lot of samples scenes can can be launched synced.
3: selecting the scene num5 which is in the same columns of scene1, just 1 row below(still the same name) and loading another preset, it loaded another sampler instance in the main mixr page, but then when playin the first scene, it played both audio together… Also they share the same midi channel, idk if it matters or not, if its the normal behaviour or not.
I think to take one of the two samples off I have to delete the main sampler associated with it.
It’s a bit convoluted but it’s ok.
4: in Arranger the first two scenes got out of view, It starts from scene 3 up to 16, and idk how to move it back so I can see the top two scenes again.
5: I have no idea what the arranger “blocks” do still… I’m trying to learn the manual and experimenting a lot I think it has smthing to do with song mode but it’s also some sort of snapshots?? Cool that I can trigger scenes with midi channels polyfonically with an external seq
(Sq64, which I hate, but it’s the best I got 
Last but not least, yeah, would it be possible to make a simple Mixxx like scratch mixer where we could mix two tracks (mp3 or wav) and then add like mixxx some extra audio clips slots for extra Synth sounds, and audio fx??? In theory it just need to convert two clips into some round turntables looking things, add a couple of faders and leave like a bottom row of 4-8 clips under the decks, plus another one or two near the faders for the fx-s…
Mixx skins works very poorly on 600p screens… Cheers!!! Great work!!!
My also first patch for Zynthian is a seq patch! (I guess the Audio samples aren’t included)
