Orchestra Enigmatica is an instrument based on samples from vintage analog "orchestral" synthesizer, Siel Orchestra from 1979 (first version). There are some additional voices created with 1984 Sequential Circuits Six-Track.
The instrument has 16 voices, which can be processed individually by adding filters, effects and modulators and then combined to create new sounds. The samples are fairly detailed to preserve quirks of an ageing synthesizer. Sustained sounds have been looped by hand, without crossfading to preserve the original vibe.
Orchestra Enigmatica comes with multi-arp function, an advanced arpeggiator, which can populate up to eight arpeggio patterns simultaneously from a single chord. Arpeggios can play different voices, run at different rates and pattern notes can be transposed with optional snap to scale function. Additionally each arpeggio has its own velocity and pitch sequence. Arpeggios can run in parallel or can be sequenced, as in "x steps of arp 1, y steps of arp 2". Arpeggiator programs can be saved to a keyswitch and recalled while the sequencer is playing. Also there’s keyboard split function, you you can play arpeggio with one hand and sustained notes with the other hand.
Orchestra Enigmatica is vintage orchestral synthesizer instrument paying homage to early synthetic emulations of traditional acoustic instruments. Those sounds mostly required a vivid imagination and a kind of positive enthusiastic approach to hear the similarities to emulated instruments. However, as the time passed, they grew a charm of their own, becoming a different type of classical instrument. While ‘Orchestra’ stands for a kind of historic exhibit, ‘Enigmatica’ hints a bit of experiment and innovation. The instrument features unique multi-arpeggiator function. It can populate several arpeggio patterns from the same chord, which can run at different rates, different rhythms and different algorithms. Arpeggios can run simultaneously and/or be mixed together creating complex note patterns from a simple chord.
