Orla DSE-24 & 12
Dynamic Sound Expander (1980?)

Italian FM expander from the eighties rebranded from the German model Böhm 12/24 originally based on Yamaha FM chips.

There are 2 rackmount models:
- DSE 24: voices polyphony
- DSE 12: voices polyphony.
There are 2 DSE versions with different design: a black one and a grey one.

Note: we do sold this machine long time ago, if you want to add something or some contribution (patch, sounds, documents) just drop us a line.

(LIST DIAGRAM).

 

fm synthesis



edit
FM SYNTHESIS concept is close to 4OP Yamaha TX-81Z concept but with only sinewave and thus 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 8 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.



lfo LFO 2 delayed modulators with variable depth amount and 2 destinations:
- LFO amplitude
- LFO pitch.



fx ENVELOPE
up to 5 EGs:
- 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.




performance PERFORMANCE
up to 16 parts with some functions:
- monophonic mode with glide option
- voices stack
- detune mode.



fx EFFECT
internal analog chorus based on BBD TDA 1022.

comment


REVIEW "Minimal interface, hard to edit and NO editors around! The DSE sounds with its own character, the analog chorus is a good point "
