Grp Synthesizer A2

0 reviews - 1113 views

Description

A little great analog synthesizer with all the Grp heritage of sound and capabilities. Wide 8 vertical space in 5U format or, if you prefer, optionally rack mountable, with a wooden sided dedicated cabinet, the Grp A2 Analog Synthesizer has MIDI In and Analog CV/Gate connections.

It offers two big oscillators with the classic analog waveforms from Grp, Plus Super Saw and Super Triangle; the great 12dB/Oct ; Grp State Variable Filter, one Ring Modulator (have you ever tried to ring modulate a 9-components Super Saw?), One Noise Generator, one Amplifier, one Master Out section with a couple of gorgeous analog VU meters.

There are a couple of Envelope Generators, the Filter-dedicated one with Looping capabilities as on big Grp A4 Synth and a couple of LFOs/Modulation Routings. The on board Arpeggiator can be clocked by Internal Clock, External Analog Clock or MIDI Clock; easy and fun, it's a breeze to use.

Grp A2 Analog Synthesizer is built like a tank. But is far more dangerous.
