Hi folks,

This thing has been in my mind for a long while, since one of the bottlenecks in SynthMaster was that the oscillator outputs were MONO To get a full STEREO sound you'd have to use Unison. Which sucks in a way, because the unison implementation wastes filters, and hence CPU cycles.

So, this weekend I did some experiments with stereo oscillators & filters. The results are really good. I even compared similar patches with Sylenth1, and I can tell you guys that SM performance is head to head with Sylenth when you use "Large" buffer sizes!

This is the good news, the bad news is changing the entire architecture from mono to stereo means rewrite of every oscillator/filter function. It's trivial yet time consuming, and will take around 10 days. Anyhow I feel this is a real necessity before the 2.5 release, especially if we're trying to become an "ivy league" synth...

EDIT: We're not trowing away unison, it's still in there. I'll have to edit all the existing 2.0 presets that use unison though, so that they use way less CPU.

Happy holidays everyone!

Bulent

I just hope there is financial reward or at least justification at the end of this.

Good news Bulent!

BTW, I'll add "Voices" and "Stereo Spread" parameters for "Basic" oscillators so it'll be very easy to setup stereo hypersaws

Any chance we could get coarse tune on individual additive oscillators to make some nice stacked oscillators?

Actually, I already implemented that in v2.5.1.45 as well, so the discrete frequency parameter is between

1-32 (integer)
1-24 (semitones) -> can increase that to more octaves if necessary.

Man, this is really time consuming. But I've gotto do it before the 2.5 release!

I need to say, that I find SynthMaster already to be very CPU friendly, beside Unison. So this feature will make it even more efficient. I think you're on the right track. The ideas of upcoming expansions seems decent and I'm really looking forward to the new presets to come with the final version 2.5! Partial presets factory selection also

Keep it up, Bulent

Well, as long as I can handle 2+ projects & 2 kids, I will keep it up, no worries

Here's the first update on this topic:

As you see above, we have 3 new parameters for the basic oscillators:

1. Voices: how many voices will the osc play? Each voice has the same wavetype, phase, volume, but different pan/detune, ajhustable using stereo/detune parameters.

2. Pan, Stereo: "Pan" is used to pan the osc. "Stereo" is used to spread the voices around the "Pan"

The detune parameter is used to spread the detune of voices, when voices > 1

And here's a sample pad with: 2 osc, each with 8 voices (so 16 voices are playing for each note), plus an analog LP filter.

http://www.kv331audio.com/synthmaster/s ... Analog.mp3

for 3 notes, and large engine buffer size, max CPU is %8 on my 2.1 Ghz MacBook.

BTW, I can not imagine creating this with the previous versions of SnythMaster, and even if I did, it'd eat A LOT MORE CPU.

BTW, I'll implement the above change for the "wavescanning" oscillators as well!

Do you ever sleep???

You really turned this into a monster in the last year.
I wish there were more developers working so hard for their products...

Once this is ready, you have fullfilled nearly every wish, one can have for a synth...

Gratulations, I hope, this brave effort will turn into a lot of cash for you.

I wish you a very happy and sucessful new year.

Thank you very much for your encouraging comments! I hope 2011 will be a good year for all of us

But... first comes health, success later, so maybe I should be careful with my sleep

stereo oscillators: a new chapter in SynthMaster, no more unison, yippi!
