MiniFreak is a six-voice polyphonic hybrid synthesizer with two digital sound engines per voice and polyphonic analog state-variable filters. It offers 31 oscillator modes, a flexible modulation matrix, three FX engines, a 37-note velocity-sensitive keybed with aftertouch, and deep integration with the MiniFreak V plugin. Suited to sound designers and performers who want experimental digital timbres combined with analog filtering and hands-on control.

★ Ideal for

Not an analog synthesizer; however, its metal chassis, universal PSU, and robust build quality (metal housing, 37-note keybed, 2.94kg) make it durable for long-term use.

The OB-6 is a 6-voice analog polyphonic synthesizer with two discrete VCOs plus a sub-oscillator per voice, a two-pole state-variable filter with multiple modes, dedicated ADSR filter and amp envelopes, and advanced modulation (X-Mod) and dual effects. It features a knob-per-function front panel, 49-key semi-weighted keyboard with aftertouch, polyphonic step sequencer and USB/MIDI connectivity, suited for studio and live performance. The sound blends classic Oberheim SEM character with modern pe

★ Ideal for

Ideal for long-term sturdy use because it uses discrete VCOs and discrete voice-card analog circuitry with a robust metal and wood build and a 49-key semi-weighted keyboard, providing durable, serviceable analog voice cards.
