mididelay is an implementation of traditional delay effect adapted for the MIDI data. It features: • 8 independent delay lines with feedback • Each delay line can process MIDI notes, control change, aftertouch, polyphonic key pressure and pitch bend messages. • For the feedback, the “feedback level” is applied to the messages; note messages change velocity and all other messages can be mixed with previous values using one of three modes (average, minimum and maximum value) • It’s possible to organise delay lines in different possible ‘algorithms’, sequentially and/or in parallel • There are three effects available inside delay’s feedback chain: scale quantise, pitch and velocity value operations randomisation • Each ‘preset’ contains 3 independent scenes marked “A”,”B” and “C”, it’s possible to cross- fade between them and adjust overall amount of the effect with 2D pad. • Simple mode : only one delay with scenes morphing. Standalone and AUv3

Take full control of your MIDI experience with Note to Be—the powerful iOS app designed to transform how you interact with your music. Whether you're working with a MIDI keyboard, sequencer, or MIDI CC input, Note to Be ensures your notes are perfectly quantized to the nearest selected note, allowing you to craft precise, harmonious compositions with ease. Key Features: - Customizable Note Selection: Choose individual notes from any octave, or apply your selection across the full -1 to +8 octave range. - Octave Flexibility: Work within the entire octave spectrum, selecting and unselecting notes with a simple tap. - MIDI CC Integration: Use MIDI CC from hardware controllers or apps like ShiftBud to convert control changes into quantized notes. Easily create chord voicings and dynamic live performances. - Multi-Synth Support: Assign different MIDI channels to multiple synths, allowing each to respond to the quantized MIDI output independently. - Live Performance Enhancement: Engage the 'all notes' toggle to instantly apply note selections across all octaves or quickly select notes in a specific key and scale. - Microtonality: Select a microtonal scale from the Scala Library with +5000 microtonal scales, or import your own to the iCloud folder. Play the MPE supported synths polyphonically. With Note to Be, your music becomes a canvas, and every note is a brushstroke. Unlock new creative possibilities and refine your sound with the precision of MIDI quantization, right from your iOS device. Note to Be is a MIDI app and does not produce any sound on its own. You need a MIDI input source and an audio output destination in order to work with Note to Be. The AUv3 plugin requires an AUv3 host app such as AUM, Logic Pro for iPad, Loopy Pro, Cubasis, Nanostudio, apeMatrix, Audiobus etc.
