- I first noticed that the main volume taper seems a bit too linear: most of the change is in the first 1/4 turn. When I found some OB-Xa patch sheets and starting entering values from it, I noticed that knobs on the obxd end up being in their lower range, sometimes within mm's of completely OFF to make sense (esp with the modulation) while the patch sheets show the controls higher up. I think there might be something off because there seems to be generalized cramping of useful values towards the beginning of the controls; of course without a real OBX in front of you it's difficult to confirm a proper behavior but IMHO I think some revue of this is necessary.
- I find the Noise source could use +3 db peak more to match the osc outputs. Peak levels match but there's quite a difference in RMS value. But maybe the current level is within the OBX spec?
- There was some discussion last year about including the additional -Xa LFO waveforms as well as an LFO re-trigger option... both of these would help make it possible to use the LFO as an additional envelope (esp Saw). I hope these aren't flushed; there's a nice spot open on the GUI for that LFO re-trigger button...
- I asked this yesterday but it didn't get answered: is the LFO in the OBX series always monophonic (1 LFO for all voices)? It would be very powerful to have a separate LFO for every voice, triggered separately for every note.
- I know this is settled, but after working a while the fact that OSC 2 detunes only in a positive direction is a bit annoying when in x-mod mode and having to change OSCs Fq an octave to test... and back... the Alt control would make it possible to have the same range and resolution available over half a turn anyways... just saying...
As usual, take or leave my comments as you wish. Thanks!
Noise source knob covers ob-x && obxa buttons.
Obxa doesnt has additional lfo waveforms and lfo retrigger. Actually those feature were introduced in ob8.
OBX series never had polyphnic lfos.
Xmod is quite rarely used feature and ob-x never had a knob. Also carrier and modulator signals are reversed in obxd(to open nice chunk of sounds when both sync and xmod are used). So you will have to do fine tunings with pitch knobs anyway ( compared to ob-x).
Filter key cv with transpose behaviour is not a bug.
