Pittsburgh ViLFO + Bananalogue Serge VCS + A.S. rs95e oscillator

Here's the Pittsburgh ViLFO (voltage-influenced LFO). In this video the
ViLFO is modulating the pitch of an Analogue Systems rs95e oscillator.
The ViLFO is being modulated by a pair of Bananalogue Serge VCS
modules. We're creating a three-way modulation loop with the ViLFO
which can yield some really nice results.
