Caustic Song file (optional):
So.. On a different thread, it has been said, today, that PCMsynth is not a synth, but a sampler..
That's not so false, especially when we know how we use it..
But let's look at the front panel.. What do we have ?? :
A sound source.. (The sample reader)..
Modifiers (Filter and Amp)
Time variable commands ( 1 LFO, 2 ADSR envelopes)..
Doesn't it sound like a basic synthesizer ? But with a more complex waveform..
Instead of loading a large instrument sample, we can load a square wave, a triangle or a sawtooth, or a sample of white noise, and we get a (basic) synth.. Like the Korg MS10 ?? Ahem.. No.. This one was nothiing interesting.. Let's say.. Like the KAWAI 100F.. That was a good simple synth..
But of course the sample can be a more complicated waveform.. Say, like on Ensoniq ESQ'1, one cycle of a piano waveform.. Or one cycle of a female choir waveform.. Can even be multisampled.. Except that ESQ'1 had 3 oscillators.. And a bunch of LFOs and Envelope generators..
So what I did this afternoon is :
1) Open the bassline.. Select the square waveform.. Set the PW knob to its middle position.. Direct the LFO to PWM.. Adjust LFO rate and level .. Set the filter cutoff to its maximum, and resonance to zero so that I keep a maximum of harmonics.. And envelope depth to zero too..
Now I had a monophonic unfiltered PWM.. Nothing so exceptional.. Especially in the high notes, where there is some aliasing.. I would have been wiser, using the modular ? Probably..
2) Open the "TOOLS" tab, and select "Merge Rack to Instrument"..
Export the PWM sound to PCMsynth.. I choosed to export from C2 to C5, every 2 semitones.. Sound is called PWMWMWM.. That's graphically nice..
I multisampled, to avoid having a PWM rate that would follow the note plaid on the keyboard.. (ie, a PWM that would be 2 times faster when you play one octave higher.. ANd 4 times faster when we play on the even higher octave.. etc..)..
3) Then I opened PCMsynth, loaded the PWMWMWM preset, worked on the loop, so that I only keep one cycle of LFO, on each sample..
Now.. It's done and saved.. I can apply low pass, band pass, high pass filters on my polyphonic PWM sound.. I can also have this filter,, modulatd by LFO, and ADSR.. I can also have the amp modulated by LFO, and the other ADSR.. I can even modulate the pitch with the LFO..
So.. Is it not a synthesizer ???
The caustic file included in this post, contains the bassline "PWM" preset which I made and used.. It includes the PCM PWMWMWM sound that I made by importing samples of the bassline's "PWM" preset.. And a few examples of the same PWMWMWM sound , modified by the filter, envelopes and LFO.. But these are just examples, other sounds can be made with this base..
Because of the size of the file, it has less instruments than on the ogg file.. They were done with the same PWM sample.. But at least, you have the bass..
You can download the caustic file and save those sounds and use them the way you want.. You can use PWMWMWM as a base that you will edit, to create your own sounds..
Have a nice evening..
