after 2 years of work, reading and most importantly, understanding the manual of the analog optimod products ive made an optimod 8100 equivalant preset. i made 2 versions, the first being pure 8100 and the second version the 8100 with the XT2 chassis

the first preset replicates the audio chain of the 8100 almost exactly (well not realy as it is comparing DSP to analog). the audio starts out at the phase rotator, goes to multiband1 as the dual band compressor, the multiband2 as the HF limiter and the clipper.

the XT2 version is the same as the previous version, only that the 2 band compressor uses 100% band linking with longer release time and multiband2 is replaced by a 6 band limiter.

The timings, thresholds, gating, crossover frequencys and many things was copied from the manual with lots and (i mean alot) of experimantations and testings. because i dont own any orban products, i am relying on radio stations, videos on youtube and stuff like that to make my preset sound close. because the main intention of this preset is to replicate the audio chain layout of the optimod processors, it allows me and everyone to experiment and allow their station to sound like an optimod.

because the optimod 8100 operates at its best at a max gain reduction of arround 25db, i made stereotool do a similar thing. the frequency ballance of the multiband2 in the XT2 preset still needs some work, if someone owns an XT2, please help and improve it.

this preset may not entirely replicate the analog and warm sound of an optimod but if you could make it sound close, thats a good job done.

You know that MB1 is not INF:1 right?

10:1 are from the limiters/Multiband clippers not for multiband compression.
You can not change ratio on the 8100,even the newer Orban boxes.

See thats the problem i have when i am trying to replicate audio processors in S.T. ill make more improvements.

when i try anything below inf:1 for MB1, it does not preform the compression properly. 10:1 is used in the 6 band limiter so for the XT2 preset, MB2 has been changed to 10:1

its normal (any optimod user, please correct me if i am wrong). optimod 8100 produce arround 25DB or so peak gain reduction and i adjusted the dual band compressor so it roughly produces that much with a sinewave input at the highest peak input level. its very dificult to get any consistancy and avoid excessive clipping when the compression is lower.
