DX1, TX7, TX816. If polyphony is an issue for

you, navigate to the DX Simulator's "EDIT LIST"

view - there you will find the UNISON Switch. Set

this to OFF and you will have 16 note polyphony

on the sound. For those of you wanting more

polyphony for the FM sounds, you can add a

second or third PLG150-DX board to your S90 and

activate the POLY EXPAND function found in the

S90's UTILITY mode/ F6 PLUG/ SF1 Status. The

UNISON POLY mode is about timbre – many of the

sounds are musical effects and polyphony is not

such a big issue.

Because of how musical sounds and 'stuff'

generated in the DX engine, the programmers

would use a 2-operator stack (minimum) to

generate a complex tone. This is why an item like

the TX-Rack became so popular at over $4,000 –

it could be expanded to house eight DX7 modules

called TF1s – that's eight 6-operator engines. The

TX816 original Voices sets, (and Yamaha only did

one or two official Voice sets), had great detail.

There was a Rhodes sound that had 24 different

sound components, including the knock of the

hammer, the tine, the tone bar, the 'fling' of the

felt, etc. It was a real shame – but most recording

studios owned TX816s, but no one ever did any

real programming beyond stacking a sound eight

times (which really only made it louder). Then

they would compound their lunacy by detuning

each module up or down a tuning increment – this

'bad' programming accounted for most of the DX

Rhodes sounds you hear on records from the '80's

– poorly utilized and was mainly responsible for

the misconception that you had to layer sounds

because FM was thin. Not necessarily so! What

was done in the original TX816 program was the

additional modules were used for details (knocks,

and noises...i.e., the "stuff"). Oh well. So many

were sold that it was inevitable that it would be

misunderstood.

you turn the POLY EXPAND parameter to ON, the

"Stuff" is a word that was adopted by the early

programmers of FM to describe a noise or artifact that

accompanies the creation of a musical tone. It's the

acoustic noise inside a Clavinet as the hammer releases,

it's the quill falling back on a harpsichord, it's the finger

noise on the acoustic guitar string, etc.

what it says – it allows you to expand the

polyphony. If you want to layer sounds to get

more complexity you would leave each 16-note

engine as a separate synth and program them

separately.

These sounds were derived from the

The LOAD:

in boards you have two files. One is the custom

PLG150-DX Board Voices that will load into the

board's own user RAM bank (035/000), and the

second is the S90 level Voices that I created to

show off these sounds. Remember the DX7 had

no effects processor of its own (they didn't exist

back in that day, circa 1983-88), so the S90 level

PLUG-IN VOICES use the custom DX board data

as the waveform but frame them with the

powerful functions and effect processing of the

S90. Truly the best of both worlds – I have

provided the "PluginAllBulk" for the three possible

slots (.w2b/.w3b) – load through the type for your

board's slot; an additional file that can be opened

in the DX Simulator for those interested in

exploring deeper into FM programming (.dxc).

This contains the same data but allows you to see

the edit parameters – provided strictly for those

that want to learn more about FM synthesis. Plus,

of course, the S90 level Voice data in an ALL

DATA file (.w4a/.w5a).
