Yamaha AN1x pure - Demo 1

YouTube via DrSqu

"This demo i made with audiotracks in Logic sequencer. Every sound is a audiotrack. All sounds drums fx etc. are pure from Yamaha AN1x. No add of external FX, or dynamic FX, used internal DSP.

Yamaha AN1x is often underrated because it seems behind the poor plastic cover being nothing. Of corse, in basic it's never so powerfully like a real old analog synthesizer. But with some tricky rules you can create fat sounds. It's also not another virtual analog synthesizer, it make some other strange, funny and mindblasting sounds ... and noises :)

YouTube via chamberofsounds
"Bubbles (#001) is one-of-a-kind battery-powered (1-9V), mini Theresynth™ with 1/4″ output, built-in speaker & incredibly spaced-out, analog sounds, handmade with love in the wild Arizona desert. Shes solidly built to last in a rugged, spaceship control case, with retro-bubbly graphics, oversized Moog knobs, high-quality photocell, momentary/latch trigger and green LED. The knobs control pitch & speed respectively, the LED corresponds to the oscillations. This is the nicest and most musical Theresynth™ Ive built to date and there definitely wont be another one like it so dont miss out! Check it out and more @ chamberofsounds.com"
