Radikal Technologies Spectralis Demo
Title link takes you to a demo made solely with the Radikal Technologies Spectralis via Zamise in this VSE thread.
ALTAIR-231
Title link takes you to shots via this auction.Details:
"Synthesizer is based on 3 VCO (any can work as the modulator), 1 VCF (lowpass 24dB/oct) with ADSR, 1 VCA, 3 LFO, noise generator (white/pink), portamento. Consist of 5 main sections - MODULATION, OSC'S, MIXER, FILTER and AMP (called Contour). "
Vintage Allison Labs 2DR

Details
"VARIABLE Hi-CUT and LO-CUT RACKMOUNT FILTER. It is hard to find much info out there about these, but I did see that recording artist John Vanderslice mentioned incorporating a similar, less feature packed Allison Labs filter into his recording setup. This is a passive unit, requiring no power cord, and all connections and controls are positioned around front. This unit IS VERY HEAVY, and VERY STURDY- extremely well made."

Cool Synth Solo
via Bitexion on this VSE thread:"Check this out, it's from a DVD of Ritchie Blackmore's Rainbow from 1984. They had a true virtuoso keyboardist. Check out his part of the stage.
And the solo [mp3]
I don't know what the two synths below the Memorymoog on the left are (there are more closeups of the MM during the clip).
Here's a breakdown of the solo since you can't see it. The pipe organ is the EMU Emulator, very good pipe organ sound. He uses both hands all the time like a true keyboardist. On the funny classical part he triggers a MIDI sequencer that sequences the bassline and chords from the Oberheim, and play the lead lines on the Hammond and the mystery synth below the big Memorymoog with each hand. The drum bit is a drum machine I believe, and the beow beow beow bass sound is also sequenced.
Onto the massive Taurus/Minimoog part..He steps on the Taurus, plays the crazy guitarlike solo on the Minimoog (truly raping the keyboard) and the strings bit again on the mystery synth. Maybe it's a strings synth. I love the way he uses delay as a second instrument, bouncing off it. Makes the Minimoog sound like an electric guitar in the Jan Hammer style. I think there is some distortion on the Mini aswell? He also uses portamento heavily in the last part. And we even enter FM territory (audio rate modulation of the filter) at the end.
On the final explosion he jumps around and bangs the Memorymoog. I have tried to play off the delay the way he does, and it's not an easy thing. You need 100% steady timing or the entire thing is thrown off track."
mp3 mirrored here for when the thread goes down.
Buchla 259 and 261e
The following notes comparing the original Buchla 259 and the new 261e Complex Waveform Generators came in on the Buchla list via Ezra Buchla, Don Buchla's son. Note the reference to the 258 Dual Oscillator.
"the waveshaping circuits of the 261e and the old 259 are very very very close. they "sound the same." except that the old one is indeed hotter, and the driving sine wave is not quite as clean or as stable in pitch.
to me, the functional difference is in the mod osc section. there are tradeoffs. the 259 has nice smooth cv output and you can push it to very low frequencies with cv input. this is good. the 261e has an additional, quite radical waveshaping circuit on the mod osc itself, which allows you to crossfade between sine, square, narrow square and a kindof funky sinusoidal trapezoid. this is good too. listen to the phase locked mod osc audio output! that is not the same, at all.
phase lock behaves differently. there are more possible behaviors in the 261e, as the process can receive certain information from software-land. and these again can come out as very interestingly close spaced chaotic orbits.
experiment with frequency modulation + pitch tracking + phase lock for maximally intricate orbit-space!
we will not do a 259 clone anytime soon. oh well.
i do luv me a 258. now THAT's buildable. of course maybe not by me, just at the moment... i am busy!
