Because it has such short and controllable delay times, unlike a typical analog delay, it can be used as an additional oscillator.Īalto’s filter is a state-variable topology with mixable simultaneous outputs, a more resonant take on the Oberheim SEM filter. You can turn the vactrol response down to instantaneous, or up to a pronounced ring.įollowing the lowpass gate is a patchable waveguide / delay module with a waveshaper and a peaking EQ built into the feedback loop. The vactrol equation slows down the response to incoming control signals through a complex nonlinear filter. This topology makes it easy to build complex, evolving textures.Įach voice also includes a lowpass gate module with a vactrol emulation in the control path. Each voice has a separate, built-in sequencer with a patchable, independently controllable rate and offset.
These sounds are uniquely malleable and alive, in part because they are made with dynamic calculation, not static wavetables.Īalto is designed as much for sequencing patterns as for playing individual notes.
The heart of Aalto is a complex oscillator inspired by Don Buchla's designs, with FM, timbre and waveshape controls that enable a wide range of expressive sounds. Aalto’s sound engine lets you create sounds that have been difficult or impossible to make with softsynths before now.
