SimplyTremolo vs Rainbow Delay Usage & Stats
A simple but straightforward tremolo audio effect to give you that nice "Crimson and Clover" feel. The controls are pretty simple and straightforward:
• Rate control -- how fast to change the incoming signal
• Depth -- how much to change the signal
• Dry and wet mix -- amount of original (dry) and changed (wet) audio to send out
• Square switch -- change amplitude abruptly instead of with smooth sine
• Odd 90° switch -- affect L and R (odd) channels with orthogonal LFO signals.

Rainbow Delay is a polyphonic harmonizing delay effect unlike any that you've played before. Harmonize full chords with multiple different intervals at once to create colorful soundscapes you didn't know your guitar could create. Program your MIDI controller to control your harmonies and delay in real time. Switch it into Mono mode for vocals and other monophonic instruments.
F e a t u r e s:
• Fully polyphonic harmonies - WORKS ON ALL CHORDS
• Separate harmonies for real time input and delays
• Delay with feedback, filter, time division and tempo sync
• Creates harmonies above and below the input signal - mix and match them to taste
• All parameters are MIDI programmable
• The stripe in the middle contains buttons that can switch modes, shift intervals and sync to the host tempo
• The colored knobs adjust the volume of the harmonies on the input and the delays
• The gray knobs adjust the delay parameters
• Shift intervals on the fly with automation or MIDI input for greater control over your harmonies
• Mono mode for vocals or monophonic instruments
• Bluetooth MIDI compatible
