Big Blue Piano VSTi: Big Blue Piano is a virtual “electric” piano - similar in sound to the Fender Rhodes. At the moment it is extremely minimal, with no GUI based controls at all (other than the keyboard). However, vibrato can be controlled with the Mod-wheel MIDI cc. Channel aftertouch affects vibrato strength, and speed.
Currently this is Windows PC only. It was developed with the JUCE open source framework.
Features:
Minimal interface
Responds to channel aftertouch, Mod-Wheel(vibrato), Pitchbend
Free!
If you need an electric piano but are looking for something more than the usual Rhodes or Whurlitzer clone, then Clavia Lab is the instrument for you.
This is a hybrid analog/physical model using experimental techniques to create the complex changing harmonic content of an electric piano. Features include:
source, amplifier and modulation sections give you plenty of control over tone and play dynamics
precise control over all parameters - knobs have around 120 steps
VU meter indicates when tone is likely to distort (distortion is actually very pleasant in most cases)
8 presets plus room for 8 more
lots of potential for experimentation.
