Check out the synth I just finished building!

I've made stuff like this before but on a really basic level. This is the first synth which I can get "proper" results from.

Specifications:

Oscillators - Each one is tuned to C but detuned very slightly so the more of them you turn on, the richer the resulting sound is. Each one has an on/off button and a volume knob. There is one big button which will play all oscillators which are turned on simultaneously. It is the only "key" on the "keyboard" and, as a result, the whole synth can only play the note "C".
12 Sine Wave Oscillators
12 Sawtooth Wave Oscillators
12 Square Wave Oscillators
Volume knobs: +/- 16dB

Filters:
Low-Pass Filter Only
Cutoff Knob - 25KHz - 15Hz
Resonance Knob - Not sure about this. It goes from "quite a lot" to "seriously harsh".

Amplitude Envelope:
Attack and Release only - so the sound stays at the same level from the end of the attack to the start of the release point.
Attack - 0.05ms - 6.55s
Decay - Fixed on 100%
Sustain - Fixed on 100%
Release - 0.05ms - 33.15s

Filter Envelope:
Attack - (Same as Amplitude Envelope)
Decay - 0.05ms - 6.55s
Sustain - 0.05ms - 6.55s
Release - (Same as Amplitude Envelope)

Noise Floor: Fluctuates randomly from -80dB to -90dB. Averages -84dB

Oscs/Ext. In ----> Amp Env ----> Filters ----> Computer

As mentioned above, the synth only has 1 note - C - so you'll have to pitch the result around to get other notes. There is an "external input" on the filters so that you can record a note without any filtering, make a chord within a computer programme by re-pitching and feed the result through the filters to give the impression that the synth can play more than one note at a time, to avoid the problem of any filter sweeps being mis-aligned when re-pitching occurs. In the zip file, the 3 chords you hear are created by this "sampling/re-pitching/external input" method. The second chord has also gone through a flanger & phaser I made:

Chord 2: Computer ----> Ext. In ----> Amp Env Bypassed (attack: 0 release: 0) ----> Filters ----> Flanger ----> Phaser ----> Computer

Chord 3 resamples chord 2 and this time it's going through the flanger and phaser on different settings (to make the sound more complex/interesting) and a stereo phaser I also made:

Chord 3: Chord 2 (repitched over 4 octaves) ----> Ext. In ----> Amp Env Bypassed (attack: 0 release: 0) ----> Filters ----> Flanger ----> Phaser ----> Stereo Phaser ----> Computer

Chord 4: Note repitched to make chord ----> Ext. In ----> Amp Env ----> Filters ----> Guitar Chorus FX Pedal ----> Stereo Phaser ----> Computer

I only spent 20 minutes making these samples so i'm sure if I were to spend longer & also use VST effects and stuff, I could get some better results.

Photos Coming soon!

cool!

sounds great!

*edit* you made it from scratch!

where do you begin? Icon_eek
sounds pretty good! really like the shimmering pad chords, nice harmonics and movement and filter sounds smooth too....

you bastard
Smile

Yeah, get yer pics out for the lads bhima.

Lol
Nice chords.
just make your own oscilloscope then Teef
where are the photos of this mythical mono-toned beast?

how soon?? :P
this the badboy?
that's fucking nuts, that horrific looking memorex cassette is the exact same type i used to record the first 'new dawn' show (signal radio, stoke on trent) i ever heard and basically captured the exact 60 mins that made me fall in love with hardcore/the breakbeat sound, PROPERLY Grin Grin Grin

(about the same time all the shelleys tapes were going around 90/91)

still have it under the stairs, badly need to record it digitally as i've been hammering it for 17 years, and it is tape after all...... haha
