such as hybrid splits between monophonic and polyphonic voices or velocity

you can also program your own modes for the EYESY

All of the original features are present: a top selection of synthesis techniques

It is possible to set the amount of exponential and linear thru-zero FM independently per each oscillator and control their amount of ‘deviation’ through two separate knobs or CV inputs

New Systems Instruments Harmonic Shift Oscillator envelop such as hybrid splits betweenThe Harmonic Shift Oscillator (HSO) produces harmonic and inharmonic spectra through all analog electronics. It provides similar capabilities to FM synthesis, but with a more direct relationship between the parameters and the resulting spectrum. You can separately control the tuning, the level of the harmonics, and the harmonic stridethe spacing between consecutive harmonics. When the harmonic stride is integer valued, you can get tones that sound
