Synchronized tonegenerator android11/18/2023 ![]() ![]() ![]() Have a look at the GSi catalog and experiment with some of the effects offered by GSi. Of course this type of instrument gives its best if run through external effects and amps. The sound engine of GSi Compact DeLuxe is also included in the GSi Gemini as well as in the Crumar Mojo 61. And this is one of those underrated details that made the sound of some Combo Organs pretty unique. a Flute 8' and a Violin 8' isn't exactly the superimposition of the two waveforms, but something slightly different. This also adds some level of phase shifting between waveforms coming from different registers, the reason why the sum between, e.g. and some waveforms also went through more than one filter. The various registers in combo organs were produced by passing the raw waveforms through a filter bank, so some waveforms were low-pass filtered for bass-like sounds, some were high-pass filtered for violin-like sounds, etc. This same technique was also used in so-called "string machines" or "stringer keyboards" that emulated orchestral sounds (violins, trumpets, etc.) - see GSi's Electrorchestra. he result was that the same notes of different octaves had oscillators perfectly in sync, so all C notes were in sync, all C#, all D and so on. At each division, something was lost and something was gained in terms of harmonic content. The lower octaves were produced by means of "divider" circuits that could halve the frequency of each waveform, going so forth for each lower octave down to the pedalboard tones. ![]() The tones integrated into it can generate binaural brainwave synchronization deploying the advanced DirectX sound system oscillators and has almost twenty brainwave frequency bands with 2X and. The basic waveform was usually something halfway between a ramp and a triangular. Isochronic Tone Generator is an effective tone-based system that basically generates strong critical responses in the brain. The electronic circuit of this kind of organ is relatively simple, at least on paper: rather than using a mechanical tone generator like the tonewheel models (Hammond and Pari), the transistor organs used a circuit called "Top Octave Synthesizer", TOS for short, responsible of the generation of 12 waveforms, one for each note of the last octave of the organ keyboard. Team R2R | 2023.07.26 | Among the many transistor organs of the past, also known as "Combo Organs" (mostly because some of them also had a rhythm section and built-in speakers), the Farfisa Compact DeLuxe, along with its big brother the Compact Duo, was one of the most used organs at least in the european beat scene of the early and mid seventies. ![]()
