I'll be honest, today I tried and failed to synthesis Well Tempered Clavier part 2. But, as a consolation prise I got a lovely deep 'cello'.
Now, instruments of the violin family cannot be synthesised in any realistic way; they are just too complex (if someone does it - they are probably using samples directly - convolution with a sample also works). However, one can (I believe) capture their essence using first principles synthesis. The key ingredients are:
- Body resonance - if you think you have too much - you probably don't.
- Pitch variation due to bowing (as the string in stretched by the bow its pitch varies).
- A shockingly rattle at the top end which somehow works out because it is unstable.
- A shimmering stereo field cause but the sound being sent in all directions by the body of the instrument.
- A strong variation of the notes as they move in and out of resonance with the body.
- A very carefully tailored envelope.
- Vibrato and tremolo which is not just slapped on but moves and is subtle.
This is the Sonic Field blog so which of these came from the Waldorf Pulse 2 and which from Sonic Field?
2 and 3 were definitely aided by Sonic Field. The reverb had a chunk of excitation to it which built on top of chorusing. This along with the alive nature of the synth (being analogue) helped create this piece. It is not a cello but people tell me it sounds nice :)
