This may take a minute or two. Please avoid turning the module off or removing the card during this time. The Crossfader algorithm now supports more than 2 inputs, allowing use as a scanning/morphing mixer. The mixer fader MIDI CC response added in firmware v1.12 has been further improved when custom min/max mappings are set. Instances of the Lua Script algorithm are now given the name of the loaded script. Added a Lua function to return the firmware version. Added a SysEx command to query the preset paths.

In the Logic algorithm: added parameters to invert the inputs and outputs; added new comparator operations; added the abitlity to chain logic operations internally to build more complex functions. Added MIDI keyboard tracking to the VCF (State Variable) algorithm.

Added the Envelope (DAHDSR), Multi-Switch, Compressor, Arpeggiator, and Poly Macro Oscillator 2 algorithms. The various Sample Player algorithms and the Poly Multisample algorithm can now record audio to memory and play that instead of playing files from the MicroSD card i.e. they can now sample instead of just playing samples. The Poly Multisample algorithm can now play a single sample chosen by the user instead of an automatically-chosen multisample. The Poly Multisample algorithm as it was in v1.9 and earlier is now the "Poly Multisample (legacy)" algorithm. What is now the Poly Multisample algorithm has the audio recording features mentioned, and is no longer multi-timbral. Existing presets will continue to load, using the legacy version of the algorithm. The various sample playing algorithms have a new custom UI for editing trim and slice points. Sample playback algorithms with start and end trim parameters, which used to be in milliseconds, now use a pair of parameters (%/fine). This is a (rare) breaking change. Presets saved with the new algorithms added in v1.9 will need to be updated. Algorithms that take a "Trigger" type reset input now cope with gate-type reset signals instead of just very short reset trigger pulses - these algorithms being: Step Sequencer (& Head), Envelope Sequencer, Sample Player (Clocked), Sample Player (Sliced), MIDI Player, and Arpeggiator.
