The digital daughterboard contains YM21280 (OPS) operator chip and YM21290 (EGS) envelope generator from Yamaha DX7 with 40 sound-generating algorithms, each a different arrangement of its six sine wave operators. It also has 3 FPGASID with same algorithms as the OPS, as well as 2x YM2151 (OPM), as well as an FPGA emulating Yamaha PS-55 and built-in 250 note samples and a room for 250 more for sample synthesis, each easily operating with a switch. Hybrid mode allows for both analog and digital sound to be output and controlled simultaneously (example one of FM chips or sample with analogue). Patches can be saveed to cassette, cartridge or SD card. Its keyboard spans 12 octaves, and the keyboard expression allows for velocity sensitivity and aftertouch. It has 2,960 programs (1920 preloaded), 1,792 combos (256 preloaded), 264 drum kits (104 preloaded), 256 GM2 programs and 9 GM2 drum kits. 100 GB internal mSATA SSD, 8 GB internal RAM (4 GB available for samples), as well as over 1000 effects, including reverb (types are Hall, Room, Vocal, Cathedral and Plate) with reverb time up to 40 seconds, delay, echo, flanging, chorusing, reverse reverb, reverse echo, ducking, ring modulation, exciter, harmonizing, equalization, pitch modification, G Major and distortion (hard clipping, fuzz or soft clipping, or a combination of those) and more. You can plug guitar pedals and/or drone synth to the synth.
You can record and play back the notes, up to 4 channels are supported. There is also an extra 'ambient' channel that can be used at the same time as playing the notes, there are 100 built-in ambient sounds (rain, winter wind, traffic, nature, savana, dark synth, jungle, space, etc.) and a room for ten more. It has several drum patterns (swing, slow rock, disco 1/2, rock 1/2, 16-beat, rock n roll, bobba nova tango, rumba, samba, waltz, heavy metal, thrash metal, waltz, jazz waltz, free jazz, hip-hop/rap, trap, prog rock, prog metal, folk, etc.)
