CV latch?

[jmp909]

Hi, is there any way to latch a CV value coming out of eg Drum Sequencer Velocity -> CV Player Tap?

specifically I've mapped the velocity from DS to the Pan on Grain Sampler, but the CV value (ie velocity -> pan position) jumps back down to 0 between steps, so it is jumping wildly up and down, instead of just swapping to the new value on the next step

Janitor can tame it a bit with the release, but it's not ideal

putting the values in raw, you can see the CV goes down to 0 first

Does it have to be Drum Sequencer? Thor's step sequencer can do this from what I recall.

[jmp909]

@dioxide, no not specifically I'm just trying different ways to send CV curves out

[huggermugger]

Can't you just use Pulsar to do it?

[jmp909]

if i wanted a continuous curve maybe, but i want to choose the values. thanks for the suggestions though, all useful.

Matrix does it fine by the way, again because it's a proper CV output

Synchronous maybe? Custom curve drawing and CV out.

[jmp909]

Synchronous... again good call thanks!

I'd still like to know if it's possible to somehow latch the CV from DS. I was thinking of taking a look at the SDK and brush up on some c++ skills

[huggermugger]

Do you know about AutoLatch? It latches gates, but maybe that'd work since gates carry velocity data.

Here's what I can do with Autolatch (and Janitor for smoothing)

this is actually weird, because it should auto-latch when you send it out as per-voice-effect. i recreated it and i dont have the issue.

if you send it out to global fx, its normal that this type of sequencer sends out just a short impulse and then cuts short. but the way you did it, velocity to pan, it shouldnt happen.

edit: or is this issue related to the cv player tap setup? i dont have that and dont know what it does.

could this do the trick? https://www.reasonstudios.com/shop/rack ... volt-sh-1/

I wish that Synchronous would have a Bipolar mode like Matrix, why the hell doesn't it?

The free CVA-7 Analyzer from Pongasoft easily converts unipolar to bipolar and vice versa.

if you're not using CV Player Tap how did you get the Velocity out of DS into the analyzer or anything else as just the curve CV (velocity value) rather than the note value?

i didnt need an analyzer, i just hooked DS up to grain and checked if a sinewave (with a long release tail) from its oscillator did those jumps and it didnt. every note stayed on its pan position, even if the next note already played on a different one.

my guess is that the inclusion of cv player tap changes DS's velocity values from a per-voice to a global application and that messes your planned panning effect up.

Yeah. Same for Pulsar. Crazy they don't have bipolar mode.

The velocity value is transmitted with the gate signal, you can directly go from DrumSequencer gate out to a CV in. This results in the jumping behavior as the velocity falls down to 0 inbetween the single gates, in opposite to Matrix Pattern Sequencer where you can "Tie" the gates together.
The SH-1 device samples and holds the last input value, this results in a Matrix style "velocity curve".

Pulsar is bipolar. It's an LFO. LFO's are normally bipolar.

Now, if it had a unipolar option, I'd be happy. But CVA-7 can fix that.

Yeah, well firstly thanks for telling about that Free RE. I'd like everything to be stock though, because I make Refills and try to avoid 3rd party plugins in these.
Anyway, all the stock curve makers should have a Bipolar mode. And Pulsar does not let you draw your own curves. Right now I ended up using Matrix, because I can draw my own curves. Alternatively I could also draw my curves with Europa.

[jmp909]

@Chizmata would you mind attaching a project or combinator with that Drum Sequencer Velocity -> Grain Pan example please, because I can't get the same result, so either one of us has misunderstood the other or I'm doing something wrong!

(note: I'm not actually wanting DS to send any notes to Grain, just the velocity curve to control the pan knob, in which case the simplest way is probably to not have them both inside the same combinator or the notes will pass through)

thanks

Thanks. Worth noting, if you look at my screenshot above of the Matrix, the CVs are not actually tied so it must latch to last value by default

Pulsar is bipolar. It's an LFO.

So it is. What the hell was I thinking? Maybe that it's not uni-polar? Who knows. Yeah, it's obviously bipolar and I've been using it for years. I'm really not sure what I was thinking. Anyway, thanks for correcting me.

LFO's are normally bipolar.

Are you saying some of my ex-girlfriends were LFOs?

If you want it stock only: use Thor for all your CV mangling (like generations of Refill makers before you).

It looks like you used the Curve in this Matrix, not the Velocity of the Gate out.
