Trend price : 70€
Italian FM expander from the eighties rebranded from the German model Böhm 12/24 . There are 2 rackmount models:
- DSE 24: voices polyphony
-
DSE 12: voices polyphony
Overview
RACKMOUNT single unit. Main panel features a simple segments display, 15 buttons and 1 volume knob.
Back panel terminal connectors:
-
master out
-
Midi interface
-
tape interface
-
footswitch input for patch increase
Voice
24 voices, hardware is based on Yamaha YM genuine chips:
- 4 oscillators operators
-
8 connection diagram algorithms
Synthesis
concept is close to 4 OP Yamaha TX-81Z but with only sinewave with no harmonic variations. 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
variable feedback strength.
- carrier: defines the amplitude and the spectral frequency
- modulator: sets the sound timbre and the relative harmonic contents.
The module offers 32 different combinations algorithms with frequency ratio or fixed frequency: the output is fed back to its input with 7 different levels feedback, as general rule, high values feedback results in richer harmonic contents.
Performance
up to 16 different parts with some functions:
-
monophonic mode with glide option
-
voices stack
- detune mode
LFO
2 delayed modulators with variable depth amount, 2 destinations: amplitude and pitch
Envelope
- 1 EG for each OP: 4 segments +1 sustain time
-
1 EG pitch and 7 preset templates
- EG scaling tracking amplitude on lower or higher octaves.
Effect
internal analog chorus based on BBD TDA 1022.
Memory
machines exists in 2 different OS versions (ROM sets):
- 1 bank of 100 patches
-
2 banks
of 100 patches

Review
OK: effect / fm / rare
NOT : edit / interface
"Minimal interface, hard to edit and NO editors around! The DSE sounds with its own character, the analog chorus is a good point "
