Self Oscillating Filters

Looking up information on filters, I found a website that had a spectrum analysis of self oscillating filters. If you need to make your software synthesizer more realistic, this website might help:

List:

Roland SH-101

Roland Juno-106

Moog Prodigy

Moog Mini

Korg MS-20

I believe the graphs show what harmnoics each filter resonates at.

Complex Envelope Trick on V-synth

One complaint about the V-synth was its lack of complex, curved envelopes. It uses linear decay and basic attack, decay sustain, and release. However, using the LFO and Key Sync you can make a much greater variety of envelope shapes

A regular V-synth envelope.

A complex V-synth envelope using an Uprising Saw, Rate very slow, Key Sync turned on. You could use this on the pitch or a filter, etc. Note the hard attack and the slow uprise. Basically we are combining the regular envelopes with the LFO.

A curved Envelope. Attack, Sustain, set to Zero. LFO Shape Sine Wave. You'd want to end the sound at the completion of half a sine cycle, otherwise its just a regular LFO. This goes for all the sounds produced in the tutorial.

Softer attack and decay and "TRP" Shaped LFO, amount not turned up too much. You may have to set a delay or a fade.

You can also use random, S&H, and all the other shapes. Remember to use very slow rates on the LFO and enable Key Sync so it retriggers. The regular envelope can be part of the attack.

New Envelope shapes = Different sounds!

Making the "Sexy Bitch" dance lead.

Here is a quick tutorial on how to make a sound similar to the "Sexy Bitch" dance lead. It uses harmonic 7ths which are also used in the classic Korg M1 organ sound. Make note of the sub oscillator.

OSC1: Juno Saw (or regular saw)
Coarse Pitch: 0
Sub Oscillator: -1 octave, level 127

OSC2: Square
Coarse Pitch: +19 (this is a whole octave and a 7th above)
Sub Oscillator: OFF

FX: Limiter 4:1 ratio, hard attack, high threshold
Guitar Amp Lead Distortion, Bass Guitar Speaker.
Reverb: Light reverb or chorus if desired.

This is only part of the sound. You could use noise in the attack if you have a third oscillator. You could also use another sub bass harmonic to be more like the original dance lead.

You can use this formula and play with it some more to get the sound you want. The reason this works in the mix is because the pitch difference of OSC1 and OSC2 allows space for other instruments or vocals in between.
