As I wanted to make Tripple-Osc sound more analogue(*), I started with the filters it uses. The important difference between the RC-type filters and the biquad-filters is the internal clipping: On analogue circuits you have to model the differential equations by using one-poles and amplifiers. While the amplifiers used for filters actually were extremely good, they could not go beyond V_max, so they clip in each stage which would go beyond... This clipped signal is fed back into the filter and forms nasty sounds or if done decently some sort of warmth... cu Stefan (*) Tripple-OSC sounds _very_ good, if you know what to do with it... The only things I really mis are: fine-detuning of the Oscillators by more than +/-100 cents and some more analogue waveforms. While the later can be just loaded into Tripple-OSC (if there was not that nasty bug preventing it to load (some) waveforms correctly...), the former can only be achieved by modifying it's source... The ability to fine-detune the oscillators by more than +/-100 cents is so important for modulating hard-synced sounds. BTW: there is another flavor of hard-sync which doesn't just reset the oscillators phase but alternates between reset to 0° and reset to 180° for each occurring "reset". The later sounds different (somewhat more harsh as there always is a phase difference betreen the new and the old cycle) and sometimes more appealing... I may put up some sound-samples of the hard-sync-modulation with and without greater range than +/-100 cents later the day, too... |
