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

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.
spectwhirl
This audio effect app transforms input sound into new textures and bell-like tones by extracting and manipulating sinewave components. It offers advanced control over delay lines, frequency shifting, and filtering, with gesture recording for parameter automation.
- Sinewave component extraction and grouping
- Delay lines with feedback
- Frequency shifter and sample-and-hold effects
- Configurable filtering
- Gesture recording for automation
- Scene saving and management

"bells and whistles, literally" spectwhirl is a hybrid spectral audio effect. It can extract and rearrange sinewave components from input signal to make new sound textures and bell-like sounds. * input sound is converted to sinewave components that are divided into 4 groups: harmonic, inharmonic, 12-edo and other * each component is fed into a delay line with feedback * there is a group of frequency shifter and sample-and-hold effects before and after delay lines * each set of sinewave components can be filtered * all the parameters can be instantly automated with gesture recording !!! Please note that this effect consumes much CPU and requires a modern device. ====================== Quick Start: Top row of controls enables different parts of user interface: scenes editor ("scene"), controls switch ("edit") and "zoom" controls When "edit" is switch on, you can show or hide various controls (marked as "ctrl") and switch gesture recording automation for some of them (marked with ">") Main control surface displays sonogram with tracked elements. Colors are set accordingly to the group they are assigned (red-orange-green-blue are for harmonic, inharmonic, 12-edo and others). Each "lane" contains delay time controls. * Triangle facing left is for the start locator, it determines initial delay time * Square moves both start and end locators together * When left locator is first moved you can see the right locator with the same triangle. It shows the end of the selected region, the secondary delay time is determined by the difference between left and right locators * if you drag over the area of the region in a lane, the four-dotted/one circle indicator will change its appearance; this changes the arpeggio mode of the region. If set to leftmost position (one circle) the components go in-sync; if set to maximum value (shown as diagonal line with circles) - components are played sequentially * all settings can be stored as "scene" and multiple scenes can be switched sequentially; there is a set of button to move, add and delete scenes. All scenes will be stored as machine state; it can be exported / imported as a single file or as separate file with current scene in the "setup" view The standalone version always starts with output level set to -70 dB to avoid feedback
