The road to version 2.0...an invitation for all to discuss

So shall we update the feature/fix request ??

Fixings:

Ringmodulator:
reshape the sine wave,
remove the "PWM" artifact at low MOD rates,
a better tweak to the MOD parameter's behaviour
make the AD levers work in real-time

Filters:
when both HPF and LPF are active you couldn't set filter's Attack time under 1 ms: please fix it!!!

PORT/GLISS slider :
make it work in real time!

Ribbon :
eliminate the glided return after the bending has been done
Set it with "pressed note priority" when SUSTAIN I is active
Sub Osc :
Better tweak the VCA amount control : it clips the thing to death when set at high values!

Global :
less digital stepping
remove crackles and pops when moving sliders

Feature requests :

Freerunning oscillators!

Fine tuning and Transpose for each single VCO per voice card

Redesigned waveforms  


In addition:

Fixing to the Initial Pitchbend needed ( to reduce the way too deeper response at high values)

Update:

Bugs:
 
1. Ringmodulator: sometimes the envelope modulation is triggered even with the DEPTH lever set to zero

2. Filters: it seems there's a small amount of Resonance going into the signal path even if the Res sliders are set to zero ( happens both with 12dB/Oct and 24 db/Oct )

Features:

1. More MIDI controls for Arpeggiator ( note #, Aftertouch, Velocity... to destinations Tempo )

2. Individual Arp for each zone !!

3. Set a better Up/Down mode ( or add a classic Roland-style u/d mode )

I don't know if it's a bug in CS80V or a bug inside mi ears, but:

When I use glissando, seems it works fine if I play high frequencies
but more I go down, more it seems sound like portamento
instead of glissando. I don't know how it sounds on original.

For exemple,if I  use a sound very pure like 2 saws and no effects,
then I put maximum glissando, then play the last key on the right, then
first key on the left I feel I could listen a very slow glissando, but when
it starts to play in lower frequencies it seems sound more like a
portamento than a glissando.

[omissis]

In my thoughts I believe this isn't a bug ,the "stepping" is less audible the more you shorten the lag time and, when glissando is very short it's very close to portamento. Maybe they may tweak the parameter but you have to think you can use it also with close to zero values so  to get an unaudible lag.

I tried your test and I hear exactly what you're describing.  But I believe the glissando is working correctly.  I think the reason for what we're hearing is that the human ear is more sensitive to changes in high frequencies than in low frequencies.  As a test, instead of using glissando mode I manually played a slow chromatic scale and it sounded the same as when using glissando.  Indeed, it's harder to perceive pitch changes on the very low notes.

In this case, I think the bug is in our ears.  :wink:

Max, I think poropat was talking about pitch, not speed.

[omissis]

Understood

I made the same experiment that you made , I didn't found a coincidence with portamento, you're right bg, there's nothing wrong in glissando ( of course not talking about the bug in the slider which doesn't work in real time  :evil:  :evil:  :evil:  :x )

Thanks bg, you are right, but when I do glissando with my
fingers in low notes, I could perceive it more than glissando
because sound is retriggered. So anyway, I think the original
works like this too.

1. Free running Oscillator I have the same opinoin. It's a big key to poly analog's real fascination.

2. please slow down the speed of stereo cooling fans. It's too fast and looks not heavily.
Make it smooth when starting or stopping fans, following the law of inertia. not a joke.

Yes , it is fundamental, together with the detunable voice cards

Question: do we really need the fans on the UI ? The original CS-80 didn't feature any fan and the inner cooling problem was one of the reasons why the thing was so weak on the tuning side ( and why each voice card drifted at different rates  :evil:  :evil:  :evil: !!! )

...Maybe it's because of fans, cooling system become better
in CS80V then, by the way sometime sound is not close to
the original... :mrgreen:

And it's because of the fans that the thing is so annoingly well in tune  :twisted:  :twisted:  :twisted:

[Marzzz]

Please add a controllable "oscillator slop" to the feature list. The original CS-80 was rarely perfectly in tune, and there should be some randomness added to the oscillators.

Save a little preayer for it  :wink:  :wink:  :wink: !!
