Update 04092018 - 3 new modules + copy paste feature + bugfixes
* Module copy paste feature has been implemented in the patcher grid (N-page) as requested by @BrettSaberhagen and others. Module parameter settings are copied and multiple-pasting is possible after pressing the copy button once.
* Bug regarding preset selection and loading (lots of turning to select next/previous preset) has now been fixed.
New Module (1/3) - Bus
We added a new module that allows you to route signals anywhere in the patcher grid, which is important if you're working on a big patch spanning multiple pages.
The new BUS module lets you do this. It has 8 inputs and 8 outputs. The input channels are summed to corresponding channels of an internal buffer, and the output channels are read from the internal buffers' channels. You can change the source and destination buffer number via the P-page (there are 64 internal buffers!).
An interesting side effect is that if you wrote data into a buffer and then stop writing to that destination, but then read from the buffer using another bus module, is that the contents are still there and will be looped.
New Module (2/3) - Switcher
We added a signal switcher module as requested by @Mercurial @IvanS and others. The switcher module has a selection input, and a signal input. The selection input is used to route the signal input to any of the 8 outputs of the switcher module.
One example application is to send a gate into the signal input and to connect the 8 outputs to the 8 gate inputs of the sampler such that when the selection input changes, the gate triggers a different sample. You can see this in action in the video below.
New Module (3/3) - Simple Delay [kickstarter stretch goal]
We added a simple delay module, with delay parameter. The delay module has a signal input and output, and simply delays a signal. It can be used of course with any signal, such as audio signals, CVs and gates, internal or external.

"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.
"short demo featuring an 8-voice wavetable synthesis patch on the percussa ssp eurorack DSP module: each voice consists of a wavetable oscillator, input and MIDI modules, envelope generator and bus module. The envelope generator amplitude-modulates the wavetable oscillator. MIDI module provides pitch, Z modulation and envelope gate/amplitude signals. XY modulation is done using the inputs which are connected to a planar joystick or dixie II LFO. The sound of all oscillators is routed via the bus module to a delay and reverb module before it goes to the output. 43 modules total are running in parallel on the SSP.
