The next generation of additive synthesis Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. The timbre of musical instruments can be considered to consist of multiple harmonic or inharmonic partials or overtones. VirSyn already has a remarkable track record of products ( CUBE, POSEIDON ) trying to make this virtually unlimited synthesis method manageable for creative sound designers and musicians. AddStation is the next step forward giving you a tool to explore completely new sonic territory. The massive amount of sine waves in AddStation - thousands per voice - together with unique morph sequencing blocks blur the frontiers between analog and digital sonic realms. And all this integrated in all relevant iOS production environments especially the emerging AUv3 AudioUnit standard.

About

Textquencer Sequencer & Synth

Create music by typing text. Each letter corresponds to a note in a chosen scale, allowing for unique melodic sequences. Customize character mappings and randomize note velocities for dynamic compositions.

Highlights
  • Text-to-note sequencing
  • Custom character mapping
  • Scale-based note generation
  • Velocity and gate randomization
  • Internal synth (standalone)
  • AUv3 plugin support

Read full description

Textquencer is a text-based MIDI sequencer. Each letter's alphabetical index is mapped to the note in the scale you are working.  For example in C-major scale, Letter A (index = 1) is Note C (first note in the scale) Letter B (index = 2) is Note D (second note in the scale) Letter C (index = 3) is Note E (third note in the scale) Letter H (index = 8) is Note C but an octave higher and so on. You can create custom character mapping for emojis, punctuation, symbols or any letters in any language. A custom character can mapped to - A specific MIDI note or, - A specific note in the scale like the first note in the scale, the third note in the scale etc. Unless a character is custom mapped, a letter in English alphabet or a number, it will be a rest in the sequencer. Also, you can randomise the velocity and gate lengths in each step if you want, You can enable it on the settings menu and set a randomization min-max range. Please note that Textquencer is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.
