Interesting info about Fusion FX chips

Postby 2ManyKeys » Wed May 16, 2018 7:04 pm

I did a bit of looking into Wavefront Semiconductor and found what I expected. This company was simply the renamed Alesis Semiconductor. Alesis did a lot of custom IC designs and I had heard about their IC division. So, here's a little more info I found.

Here are a couple of the Wavefront FX chips found in the Fusion. Datasheet downloads as well.

Here are the datsheets for the adc and dac chips. Nice parts.

I found an interesting reference on Gearslutz about these 2 converter chips being used by other manufacturers
"which are used in the Behringer ADA8000, Alesis Ai3 and PreSonus FIREstation (surely among others)"

Datasheets for the Insert and Bus Fx chips. Really quite capable little units. Just wish the delays were longer.

it's unfortunate that Alesis didn't give us access to all 8 types of reverb in the bus fx chips (the Digital Reverb Engines). Looks like a pretty nice setup. Quite a bit more flexible than the single Hall, Room, Plate setups in the Fusion.

I find it difficult to get a nice warm (realistic) reverb out of the Fusion. The warmer (darker) options that are on the chip would have been nice.

It is also interesting the Alesis used the same DRE "Digital Reverb Engine" chip in the Micron and Miniak and the delays in those machines have tempo-sync!

Grrr... I really wish that had been added to the Fusion. :-( The lack of tempo syncing on the Fusion delays is very unfortunate.
