Between the ones they have and those that are available elsewhere I think its WAY more important that Arturia redo some of their code.
I have yet to get Analog Factory to not crash on my Mac. I bought it but dont even have it installed because of this. And its even worse with the latest update.
The LFOs should be switchable between continuous and gate on the Modular.
Much better and more flexible library menus/maintenance
It would be awesome to see an effects version of the SEM filter. Its very unique and not available anywhere else.
Polyrythmic Step Sequencer like Tremor has
Most importantly they have to catch up (to U-he ideally, or DCAM) with oversampling, filter quality and envelope design.
If they did this, it would be like a new lease on life for the line.
Great synths generally but losing ground and marketshare by the minute for these reasons.
As for another synth, i would almost be annoyed if they made one without doing these updates first, but a relaunch with these updates and a Buchla with U-He quality would put them back on top again.
