"Shruti-1" - looks very interesting! Only 110 Euros when available... http://mutable-instruments.net/ Old-school technology Minimalist digital oscillators… No 800MHz ARM core, Sharc DSP or hardware-accelerated band-limited interpolation here! The Shruti-1 runs on a modest AVR microcontroller (of the Arduino fame) clocked at 16 MHz and providing a whopping 2kb of RAM. You’re more likely to find this 8-bit wonder in vending machines than in synths… Yet, the Shruti-1’s firmware squeezes the most out of this tight processor to render classic waveforms, but also FM or weird digital sounds – all of them in their full 8-bit quirkiness. ... with an analog twist! Today’s synths use DSPs or general purpose CPUs to emulate classic analog filters. To color and warm up your sounds, the Shruti-1 directly uses the real thing: a CEM3379 VCF/VCA, belonging to a lineage of chips found in the Prophet VS, my beloved Ensoniq ESQ-1 or the Waldorf Microwave. Perfect for fat basses or lively sequences.
