Percussa Adds Physical Modeling Membrane Module (PMM) to SSP

percussa ssp - physical modeling membrane module demo Published on Oct 13, 2018 PERCUSSA

"short demo for the new physical modeling membrane module on the percussa super signal processor (ssp) eurorack module - membrane excitation triggered by make noise MATHS as well as internal square wave LFO on the SSP. Power and tension modulations of the membrane using low-frequency noise generators on the SSP with offset applied via the DC generator module on the SSP. Learn more about the SSP at http://www.percussa.com/"

via the Kickstarter campaign:

"Time for another update! In this one we introduce the physical modeling membrane module (PMM) which was a kickstarter stretch goal module. We also provide an example preset to go with the module.

Physical modeling membrane (PMM) module + DEMO VIDEO

The module has the following inputs:

Gate input to trigger the virtual "hammer" that strikes the virtual drum membrane (also called the excitation)
Power input / parameter to control with how much force the virtual hammer strikes the drum
Tension to control how loose or tight the drum membrane is (controls the pitch of the resulting drum sound)
You can feed an external trigger into the gate input or just use an internal square wave LFO on the SSP if you wish. In my demo video I do both, first with a make noise MATHS and afterwards with a square wave LFO. In the video I also demo modulation of the power and tension inputs using low-frequency noise generators. The tension modulation signal is offset using a DC generator module.


Pitch tracking fixes

Pitch tracking bugs reported by @IvanS and others are now fixed for all the modules that have a pitch input
Coarse/fine frequency settings for modules with a pitch input now no longer affect tuning but are simply an offset for the frequency calculated from the incoming pitch signal. Frequency modulation received via the frequency input is applied on top of this offset and the frequency derived from the pitch signal.
If you feed a pitch signal into an LFO or other module with a pitch input, and you don't want a frequency offset, remember to set coarse/fine to zero on the p-page.

That's all for now, we hope you enjoy this new module!
