How do i perform gliding and portamento?
I would like to use this feature in my synths but i already trid to connect single sliders with huge values, multiplications and divisions but i simply cannot make the MIDI2CV portamento make a glide nor even a sligh pitch slide!
What do i have to do?
Thanks:
Duarte V.

sorry my reply was rubbish :-) was thinking of something else. got so used to having this, i guess. you can make it have a portamento on/off, by having the portamento amount switch bewteen 0 and the value you give it from the portamento knob. is this it? off/on are just fixed values outside the container, 0/1. i don't know if smoothing would be a factor, but it's in there atm; not sure what a good setting would be). i can't remember using this to do slides, but it's simple. don't know if it works used like that.  |

i dont understand the problem because there is no trick or something like this.
just connect a list entry and a slider and it works!?!?
open the PD303 prefab to look and test it!
or do you want to create a midi-out plugin?

ok..i checked PD303 .. it seems to work but only in Mono Mode = ON ...when set to OFF does not seems to work...is this a feature only for 1 polyphony or can it be use with 10 poly - reserve 4 ?

ahhh ok, this is normally working in mono mode only.
if you want a "pseudo" polyphony glide you have to use many cv-to-gates in seperated containers.
but you have to split the polyphony and switch each key to a mono-cv-gate.
this is the only way i know. maybe someone else know a better one?

how do you split out/assign the polyphony/voices?

this is sirsicksik's post on the usergroup:
"try using the voice splitter module (not sure if that one is also in
the old synthedit versions, but in the new one it is).
Combine the signals of the midi2cv:
((pitch+0.75)*12 + velocity/100), then use a level adjust to use
the gate to open/close this signal (when gate = off, result=0)
Put the result of the level adjust into a voice splitter, split up
the voices and route this to the IO module.
Then give each voice out it's own synth-container (osc, adsr, filter,
etc) where you first use a floor-module to split the pitch and
velocity parts of the combined signal. Then divide the pitch part by
12 and subtract 0.75 and multiply the velocity part by 100. The
velocity part can also be used as the gate
(as both when the velocity =0 and gate=0, signal should be off anyways..).
Use S&H's to keep pitch and velocity values the same when gate goes off
(triggered by velocity)
ps you maybe could also use the manymono2poly of daz to turn these
monophonic signals outside the container back into a single
polyphonic chain, but I'm not sure whether the module will respond
right to multiple monophonic gate signals into the gate pin.. (never
used it myself really..)"
maybe this was intended as an answer here...?

woow..i guess i was doomed...since i have 2 MIDI2CV with 10 voices each and 5 diferent oscillators on my synth... this technique would consume the rest of the CPU (i think??!!!)... i rather leave it without this kind of Portamento and keep a pitch envelope even if is not a perfect one : S ....
Thanks for the info anyway, glad to have support! : )

you can do portamento with a -6dB/oct LPF across the pitch line:
set the cutoff low, and you get a glide.

i believe i did it before but if i remember, if the user keeps the key pressed it does a long glide ending in a very high pitch... but i will try it again cause i do not remember well.... Thanks  |

midi pitch cv >-6dB lpf with a cutoff control>pitch in
i don't really understand how it works; i think the filter
acts as a 'slewer' (anyone confirm this?) for the cv changes.
you have to set the cutoff low for it to work: the lower it goes,
the longer the porta. it has a slightly different quality to the
midi to cv portamento. would have to ask Jeff what goes on in
the midi to cv to get a better notion of portamento.

lo0l..i dont know but dont higher octaves have a higher frequency? so LP is based on 1 volt/octave ... Hummm... the rest i dont know ; )
