Interactive Graphic Score & Serial Music Generator. POINTILLISME is a browser-based generative quartet built entirely with the Web Audio API — a single self-contained HTML file, no installation, no dependencies.

Four independent oscillators function as four voices in a serial ensemble. Each voice runs seven independent series that advance at their own pace: pitch (cycling through all 48 row forms — Prime, Inversion, Retrograde, Retrograde-Inversion, each at 12 transpositions), register, duration, dynamics, envelope (ADSR), spatial position (stereo pan), and ornament. Because the series lengths are coprime, the global combination does not repeat for millions of events — an arithmetic property that produces the absence of repetition and hierarchical landmarks characteristic of integral serialism, not as an imposed rule but as an emergent consequence of the system itself.

The ornament series draws from ten types rooted in traditional and extended technique: trill, mordent, gruppetto, appoggiatura, acciaccatura, glissando, tremolo, arpeggio, cluster, or none. Each ornament is rendered both in sound and as a graphic glyph on the scrolling score.

The visual output is a graphic score in the tradition of Stockhausen’s Studie II and Earle Brown’s coordinate notation: time flows horizontally, frequency vertically, each event is drawn as an envelope-shaped figure whose width is its duration, height its dynamics, and profile its ADSR contour. The four voices are distinguished by colour (sanguine, ultramarine, green earth, ochre) and by texture (smooth fill for sine, horizontal hatching for triangle, serrated edge for sawtooth, vertical striations for square). Ornament glyphs appear above or beside each event using conventional notation symbols.

Compose with it
Press play and POINTILLISME generates a continuous, non-repeating serial texture. Each voice has its own waveform selector (sine, triangle, sawtooth, square) and can be independently re-seeded or muted (tacet). The base time unit controls the pace of the generative process.

When you hear material you want to keep, press record. The instrument captures the full stereo output and all note events simultaneously. When you stop recording, two export buttons appear:
– Save audio — WAV or AIFF, 16-bit or 24-bit, at your system’s native sample rate (typically 48 kHz). Ready to drop into any DAW.
– Save MIDI — a Standard MIDI File (Type 1) with four separate tracks, one per voice (OSC I through OSC IV), each on its own MIDI channel. Drag this into Ableton Live, Logic, Reaper, or any other DAW and each voice arrives on its own track. From there, you can assign your own instruments, edit individual notes, transpose voices, or use the serial material as a compositional skeleton for an entirely new piece. All ornament events (trill alternations, glissando steps, arpeggio tones, cluster notes) are written as discrete MIDI events, so nothing is lost in translation.

Perform with it
The freeze function (button or F key) stops time: the score halts, every event visible at that moment stays exactly where it is, and the canvas becomes interactive. Click any event and it plays — with its original waveform, envelope, ornament, and pan position. This turns POINTILLISME into a live instrument: you freeze a moment, explore its sonic content by clicking individual events in any order you choose, then unfreeze to let the generation continue. In a live performance context, alternating between generative flow and frozen, manually-triggered gestures creates a natural dialogue between algorithmic process and human decision.

Bespoke is a modular synthesizer / DAW capable of hosting VST plugins.

It contains a bunch of modules, which you can connect together to create sounds. It is like a DAW in some ways, but with less of a focus on a global timeline. Instead, it has a design more optimized for jamming and exploration.

Bespoke’s core design is to break everything into separate modules that can be patched together in a custom layout, much like a hardware modular. Bespoke is designed to be highly customizable, with the idea that any of the custom layouts that you create will be “bespoke” to you as well.

Hotstepper is a 12-channel drum sequencer for Windows that’s packed with a lot of nice features.

Features:

• Adjustable velocitiy and pitch for every event
• Up to 12 different sounds can be used simultaneous
• Adjustable velocity, delay, panorama position and pitch for every sound
• Adjustable pattern size and resolution (triple, quarter)
• Import wav files (10 second max, 44.1kHz, 16-bit, mono only) into the sound libary and select start and end sample points
• Export drum patterns as Windows PCM (*.wav) files
• Delay control so you can define the amount of the delay and adjust feedback
• Shuffle control for adjusting the type of shuffle and its intensity
• Organize patterns into a song (only one pattern may play at once)
• Wave Stretching allows you to define sounds that will be stretched automatically to the length of the beat
• Sounds can cut-off other sounds when started (ie. Closed HiHat stops Open HiHat)

A pattern-oriented, polyphonic MIDI step-sequencer, which makes its own path. 16 parallel patterns with six tracks and 16 bars – equating to 256 bars & 96 tracks. The six pattern tracks imitate the strings of a guitar and will be tuned e.g. to “EAdgbe”. With some clicks you can set a guitar chord to the pattern tune – then by enabling a few events or triggers the sequencer will start a solo or plays with the chords. More offset-, mute functions and a tricky song mode will pep-up your set. With CYTHAR you can program drum sets, melodies, arpeggios and complete songs. If this is not enough try out Rebeca!

With the simple accessibility of all settings the user interface is designed for life and jam performances. The drag and drop features make CYTHAR to a powerful and fast editor. In future we want to release a specialized touchscreen version.

For now every CYTHAR Sequencer is still in development and only available as a beta version. In the download area you will find some downloads for Linux, Windows and Mac versions for different CPU architectures and different system distribution or drivers.

The file includes Windows and Mac versions.

BlueARP – VST MIDI Arpeggiator with pattern sequencer stile, designed for electronic music genres.

BlueArp is to be used as a VST instrument, but it doesn’t generate any sound itself, it generated MIDI messages, so it should be connected to another synth, hardware of software.

LUNA is a light-weight and easy to use professional grade sequencer offering VST instruments and effects support and a 32-bit float audio engine so can handle almost all sample rates. The basic features of midi and audio recording and playback are also well supported and easy to use, with multi undo and redo. The interface is also very simple to use with the program only limited by the 4 VSTi and 8 mixer strip allowance which is how it is differentiated from the paid version.
