Plogue adds OPK2 (YM7129) and OPL2 drum mode   22-Nov-22

Chipsynth PortaFM Updated

Plogue have just updated their PortaFM synth, which now features the OPK2 (YM7129) used in some rare PSS synths and a fully editable OPL2 drum mode! They claim to be the first to emulate the rare OPK2 and have added various bug fixes and improvements. The synth will be familiar to those who encountered the PSS-140 which it is visually and sonically styled upon - but adds all kinds of depth to the synth engine, including a sequencer, arpeggiater and effects, 

PortaFM uses a pair of cycle-accurately emulated FM chip cores for its main synth engine, switchable between OPLL (YM2413), OPL2 (YM3812) and OPK2 (YM7129). Another core is dedicated to the the drum sounds, and all of this can be layered creatively.

The unique 'lofi' quality of the OPLL, OPL2 and OPK2 chips was never recreated this accurately before. Plogue's experience of more than 15 years studying vintage digital sound generators was pushed to its limit. Brand new mathematical models were built using our custom Hardware-assisted systematic testing procedures by our in house reverse engineering team in Montreal.

Oh, and of course, it does not use ANY samples!
