@jeanclaudegavri: it's a Factory patch from the DSE-24 straight into reverb

The Böhm Dynamic 12/24 (and its rebranded counterpart, the ORLA DSE-24) along with the Dynamic 4x9 were somewhat unusual and very much overlooked synth expanders from mid 80's...

Originally sold in self-build kit form from the Germany organ manufacturer Böhm, both variants featured as many as 12 Yamaha YM2203 4OP FM tone generator ICs fed into a genuine BBD based triple ensemble generator with two modulating free-running LFOs.   Originally designed for use in games machines and home computers the YM2203 offered 3 channels of classic sine-only based 4-operator FM synthesis in a chip.

This unique combination produced up to 24 note polyphony in the 1U racks or up to 4 layers of 9 note polyphony in the 2U versions.

What sets these instruments aside from the more conventional 4OP FM offerings such as the DX9 is that not only does the triple ensemble generator add a whole new dimension to the sound it starts to make you view the FM side as a starting point to the final found rather than the sound itself.  With this way of thinking it is possible to generate everything from remarkably analog sounding Solina style strings to warm complex evolving pads.

11Korg Bounce

Having a go firing the little Orla DSE-24 (a rebranded Böhm Dynamic 12/24 from 1986) through a wobbly reverb patch on my Klockwerks system.  I've grown to love these little 4OP FM synths - I think it was a moment of genius to bolt on a discrete Solina strings style triple analog chorus generator to the YM2203 based synth section - the result is a wonderful complex soup of unusually organic sound for an FM synth.  It doesn't work for all timbres but over time I've had a go making some patches of my own on this thing (this being one of them) and its sometimes really surprised me what has emerged from its outputs!

this is urrovlp01,
a selection made from the digital release that global aphasia made last year.
we have been selecting a few for this for a while now.
prolly will be a few more releases like this on the way, cause i think these works need a release on vinyl.

i deeply love your work, zane :)
all the best, dom micomu

Feb2-EIBE sketch (2015)

Testing out Factory patch 90 on the curious little Orla DSE-24 FM synth module shortly after revival...

This rather unusual little module is basically a 24-voice FM 4-OP synth based on Yamaha FM Tone Generator chips fed into a genuine Solina style triple analog chorus ensemble generator.  This somewhat weird combination allows Solina style strings to be generated with ease as well as a load of other timbres perhaps not so often associated with FM synthesis... naturally, with the chorus switched off, it does all the usual bells and bass timbres too.

Probably the closest in terms of sonic palette is the KORG DS-8 but the bolted on FX are analog in the case of the Orla.

1987 Orla DSE-24 (aka Böhm 12/24): Factory Patch 90

1910_Tj

Having a play with my first patch programmed into a 1987 Bohm Dynamic 4x9 during overhaul at Hideaway Studio.

The Dynamic 4x9 was basically the big brother version of the Böhm 12-24 / Orla DSE-24 featuring the same FM based synthesis fed into a genuine Solina style analog BBD based triple ensemble generator but also included a BBD based phaser and individual audio outputs.  The FM section featured a whopping 12 YM2203 triple FM generator chips allowing 4 layered channels of 9 voice polyphony or up to 36 voices.

Unlike the 1U versions (which used the same FM chips) the 4x9 permits front panel patch editing using a rather more user friendly method with an LCD screen and data value controls.

1987 Böhm Dynamic 4x9: First Test

Having a play with my first 4-layer patch programmed into a 1987 Bohm Dynamic 4x9 during overhaul at Hideaway Studio.

The Dynamic 4x9 was basically the big brother version of the Böhm 12-24 / Orla DSE-24 featuring the same FM based synthesis fed into a genuine Solina style analog BBD based triple ensemble generator but also included a BBD based phaser and individual audio outputs. The FM section featured a whapping 12 YM2203 triple FM generator chips allowing 4 layered channels of 9 voice polyphony or up to 36 voices.

1987 Böhm Dynamic 4x9: Layer Test

A quick live improv with a newly created evolving patch on a 1987 Böhm Dynamic 12/24 recently overhauled and upgraded to 24-voice.

The 12/24 is an unusual combination of classic 4-OP FM fed into a lovely on-board triple BBD based analog ensemble generator...

1986 Böhm Dynamic 12/24: Evolution 24V

The more I play with these old Böhm Dynamic 12/24 (and rebranded ORLA DSE-24) rackmount synths the more I love them!!

Many of the factory presets are a bit weak but with some trivial editing they can really come alive like this one.

What other little rackmount offers classic 4OP FM with 24 note polyphony bolted to a genuine triple BBD based analog ensemble generator!?

This unique combo really does present FM in a different light - the result is much more organic, warm and complex in nature and its interesting because you find yourself building FM patches in a different way to more conventional FM synths in that you start to view the FM generator as an element of the sound rather than its entirety sending you down different creative paths than the usual bass and bell timbres!
