How do i make poly/mono/legato mode for portamento. For the mono mode do i need to have whole synth in mono then? Because i think its most poly synth. Can some one explain bit for me what all those modes for portmento is good for. I guess they r kinda usefull. So need help how to make those.

I did read some little about legato dident get what it does realy.

So pls help me out guys.

legato is playing 2 notes of differing pitch sequentially, without having any silence between them. So porta slides pitch, but there are attack phases for both notes. With legato, there is no attack on the second. I just looked it up too man. I know it as slurring from playing brass. hmm, I wonder how to implement, so can't help u there yet sorry.

Heya! As for the porta/mono synth: In the midi to poly module, there's a switch in the properties. When I was making a simple mono synth, I just deleted that switch and replaced it with my own. Remember to put the max voices down to one, and switch porta on 🙂

A good solution is making a glide. ( power). SM standard porta is a s**t. Only on mono. There are some amazing portamento on poly voices on Rob Papen synths. But i can't find any guide or dsp to implement in.

Yes, it's a shame that SM's poly voice management lacks more options. As it is the 'foundation' of everything using poly streams, and is an uneditable primitive, there's no way to add any extra features and still retain the nice CPU managed poly streams. However, it is possible to create custom voice managers for synths using mono and mono4 streams. Triciker to do, and you get less well managed CPU use - but there are other advantages besides adding poly portamento (e.g. True free-running oscillators, tweak parameters 'per voice'...) Here are a couple of links to my previous efforts... Green Poly Voices (4 Note poly synth - has poly portamento and unison modes) Special mono legato mode I've now got as far as an 8 voice polysynth with the "Green Poly" voice manager - I'll post that up later.
