Support for "Multisampled" waveforms in 2.1

[kv331]

Hi everyone,

I've been quite busy with sampling my Mopho synthesizer's basic waveforms (square, sawtooth and triangle) and getting those single cycles correctly into SynthMaster. It sounds like a very easy task, but no way!
There have been challenges, but I've been able to get over them!

So, how we do it?

1. Sample the waveforms at constant intervals, for instance at every octave.

2. Extract a single cycle from each sampled note, and while doing that start a couple of samples before a single cycle starts, and end after a couple of samples where the the single cycle ends. Dont forget, the start of a single cycle is a zero crossing, that's how SM will figure out the exact start-end positions of the single cycle.

3. While saving the single cycle, save it in the following format:
<waveform name>.<note nam>.auto.wav

For instance, I sampled a sawtooth waveform in 6 octaves:

Saw.C1.auto.wav
Saw.C2.auto.wav
Saw.C3.auto.wav
Saw.C4.auto.wav
Saw.C5.auto.wav
Saw.C6.auto.wav

"auto" means SynthMaster will automatically detect the cycle start/end positions in the WAV file. if there's no .auto at the end of the file name, SynthMaster assume the entire file contains a single cycle.

With this feature added, I added another important relevant feature: Let's say you have multisamples from different analog synths, MoogSaw, MophoSaw, PhophetSaw, etc... And you suddenly want to switch to ProphetSaw for all of the saw oscillators globally. You will be able to do that by changing a global parameter's value So in summary, Saw, Square, and Triangle wavetables can be globally set to specific wavetables.

I am planning to make an alpha/development release this Sunday! Will announce it here!

Cheers,

Interesting new feature

Now the SM 2.1 can not only work as va-synth, wavetable-synth or as additive synth, now also as kind of a rompler

I'm talking about single cycle waveforms though. Sample playback support will come back after our AU/RTAS releases.

I like where this is going. But it will make the existing fr4ncesco ones some kind of 'obsolete'
I'll send you a PM about a famous youtube musician who can maybe help you with multisample content.

No, why? They're good for wavescanning synthesis.

Also, I've got some plans for a "vector" kind of oscillator with 4 waveforms.
For 2.2 and beyond. We need wavetables for that kind of synthesis

This afternoon I created side-by-side comparisons of sampled vs original Mopho waveforms, here they are:

Saw comparison
Square comparison
Triangle comparison

Guess which channel is "real", which one is "sampled"? and tell me your comments!

Cheers!

Too short notes, ot easy to listen exactly

Wow, it'll be fun to use them in synthmaster! They sound kind of fat. I'm curious how will they sound with the new distortions... Analog sounds routed through distortions gives me goose bumps.

Maybe the multi-sampled waves should get their own 'premium' category in SM2?

Good to hear that you have that vector module in mind. I have an idea in where each of the 4 mixable sources would have 2-2 waves which can be morphed together with a knob. So basically the whole module would use 8 waveforms. What do you think about it?

Well, with 2.1 you have the "choice" to replace the "default" waveforms (saw, triangle, square") with any wavetable, and I set the "default"s as the Mopho multisamples

You'll have the chance to play with it tomorrow night fellows!

Guess which channel is "real", which one is "sampled"?

On saw, left channel is real
On square, right channel real
On triangle, right channel is real

?

2 correct answers! All lefts were SynthMaster.

How do they compare though?
