Trend price : 150-250€
Compact version of Yamaha DX27 FM synthesizer based on 4OP series, budget spinoff from classic 6 OP DX7 machines.
Overview
KEYBOARD (weight: 2,7 Kg / dimensions: 628 x 75 x 218 mm) 49 Keys (mini keyboard). Main pannel features a LCD
display, 38 rubber buttons, 2 sliders for data entry and main volume and finally 2 wheels for modulation and pitchbender.
Rear panel terminal connectors:
-
mono main out
-
footswitch input
- headphones out
- Midi interface
- tape interface
-
breath controller input
Voice
8 digital voices - 4 OP and 8 combinations called "algorithms".
Synthesis
there
are 4 sinewave operators organized as algorithms, assigned as carrier
or modulator, linked between them on different
pathways interacting on their harmonic contents depending on the
varable feedback strength: A) carrier defines the amplitude and the spectral frequency B) modulator sets the sound timbre and the relative harmonic contents.
Dx100 offers 8 combinations algorithms with frequency ratio or fixed frequency: the output is fed back to its input with 7 levels feedback, as general rule, high values feedback results in richer harmonic contents.
Performance
system some special performance play:
- poly / mono mode
- portamento set with time
- pitch bender range
- mode wheel r range
- breath controller setting (destination / range)
- dual / split mode.
LFO
2 delayed modulators (frequency range from 0.007 Hz to 50 Hz)
1- LFO amplitude
2-
LFO pitch
The modulators can be set to retrigger mode and features 4 shapes: saw, square, triangle and sample & hold.
Envelope
4 EGs: each OP features 1 amplitude EG (4-segments) + 1 general shift. Very simple Key tracking scale less sophisticated than previous DX line.
Memory
- 192 ROM patches
- 32 RAM patches.

Review
OK: cute compact / 4 OP fun / rare
NOT : pricey / no backlight
"Cutie-pie ! nice as many 4Op... still cannot understand why it is so sought-after and so pricey: I mean a damm cheap TX81z is same sounding with even more multitimbric power and more waveforms :) "
