Grainfold vs apeCsound

Grainfold is a granular synth that turns any sound into an instrument. Record your voice, a glass or the street outside, or import a file, and shape it into loops, playable chords, melodies and evolving clouds of grains. A GRANULAR SYNTH YOU CAN PLAY Granular synthesis cuts a sound into tiny grains and plays them back in new ways. Grainfold makes it hands-on: set how long each grain lasts, how often grains spawn, where they come from and how far they scatter. Reverse them, spread them across the stereo field, give them a shape from smooth to plucked, and play them from the keyboard, MIDI or your fingertips. FOUR REGIONS, LOOP OR GRAIN Mark up to four parts of a sound, each with its own mode, pitch, envelopes, filter and modulation. LOOP repeats a region with fades and crossfade; GRAIN turns it into textures, pulses and harmonies. MELODIES WITHOUT A KEYBOARD The step sequencer plays sixteen steps of any scale in time with the tempo. Or let every grain choose its note: random notes of a scale, a wandering line, a melody that comes home to the key, or a slowly evolving motif. SHAKE TO PLAY In SHAKE mode, balls bounce around the sound as you shake and tip your phone, like a pong ball off the edges of the screen, and the grains follow them. HARDWARE LOOK, CRT SCREEN A silver metal body that catches the light as you tilt your phone, solid keys, big knobs and a waveform on a glowing CRT screen, with bloom and scanlines. Each grain is a spark, as big as it is long. A small spectrogram, an oscilloscope and a 3D spectrogram show what you hear. LOCKED TO THE BEAT Type or tap a BPM. Spawn grains on the beat, set their length, the scan, the LFOs and the delay in note values, and see where every beat falls. A metronome keeps time in any meter. In an Audio Unit host, Grainfold follows the host tempo. MOVEMENT AND EFFECTS Two LFOs per region, ADSR envelopes for notes and the filter, PITCH that keeps timing, SPEED that keeps pitch. Filters, harmonic LAYERS, drive, chorus, DIFFUSE, delay and reverb. PLAY WITH TOUCH OR MIDI In PERFORM, each finger plays a region and moves two parameters; LATCH holds sounds and MOTION loops your gestures. Chords of up to twelve notes from the on-screen keyboard or MIDI, with velocity, sustain, pitch bend and MIDI Learn. RECORD, EXPORT, AUV3 Record your performance as a 32-bit float WAV straight into your DAW's folder. Play Grainfold as an AUv3 instrument in GarageBand, Logic Pro for iPad, AUM or Cubasis; Grainfold Capture records takes from any track. 40 PRESETS AND 20 STARTER PROJECTS Factory presets in seven categories, your own presets, and starter projects that each bring their own recording, root note and tempo. Share projects as .grainfold files. FREE, AND PRIVATE Every feature is free. No account, ads or tracking: Grainfold collects no data, and your recordings stay on your device.

apeCsound brings the full power of Csound 7, one of the most complete sound synthesis and signal processing languages ever created, inside your music apps. Write or paste any Csound orchestra, press Apply, and apeCsound turns it into an Audio Unit (AUv3) instrument or effect you can play, record and automate in GarageBand, Logic Pro for iPad, AUM, Cubasis, Loopy Pro and any other AUv3 host. It also runs as a standalone app. THE CSOUND ENGINE, BUILT IN Csound 7 is embedded in the app: nothing else to install Thousands of opcodes: oscillators, filters, physical models, granular, spectral (pvs), FM, waveguides, reverbs, delays, OSC and much more Process live audio from the host as an effect, or play it as a MIDI instrument Audio channels follow the host layout automatically Host transport available to your code as control channels: tempo, play/stop, position, time signature PARAMETERS YOUR HOST CAN AUTOMATE Describe sliders, switches, menus and XY pads directly in your .csd file apeCsound builds the control panel for you and exposes every parameter (176 in all) to the host for automation and MIDI learn Values are read in Csound with a simple chnget; chnset writes them back and moves the controls Organise the panel in collapsible groups with a comment in the code Snapshots: save, recall, rename and overwrite complete sets of values, stored with the session Undo and redo for every change, with one shared history LIVE CODING Evaluate sends the selection, the current instrument block or a single line to the running engine, without recompiling: redefine an instrument while it plays, change a global value, trigger a score event A dedicated Evaluate line for one-liners such as "i 2 0 1" SEE WHAT YOUR CODE IS DOING Monitor: every value written with chnset appears as a meter, a multi-bar card or a text line, with dB scale and history on request Channels: a diagnostic list of every channel the engine knows, with type, direction, value and who writes it; channels that nobody writes are flagged and can be mapped to a parameter in one tap Graphs: function tables and display signals drawn live, redrawn whenever a table changes Console: all Csound messages and errors, with errors marked on the line in the editor A CODE EDITOR MADE FOR CSOUND Syntax highlighting with dark and light themes, line numbers and adjustable text size Opcode completion that inserts the complete syntax, with outputs and optional arguments, in classic or modern (functional) style Jump between arguments with Tab Inline help bar showing the syntax of the opcode under the cursor, or the error on that line Find and replace, comment/uncomment, smart indentation Designed for touch: native-style selection handles, magnifier, edit menu and long-press caret navigation Built-in link to the Csound reference manual SESSIONS AND FILES Open and save standard .csd files from Files, iCloud Drive or any document provider Your code, parameters and snapshots are saved with the host project Start from a ready-made template, a blank session or one of nearly 200 included examples Import Cabbage and CsoundQt files: their widgets become parameters, their meters and displays show up in the Monitor ACCESSIBILITY Fully usable with VoiceOver: named controls, real menus, an accessible code editor and XY pad, complete keyboard navigation Whether you are a sound designer, a composer, a teacher or a student, apeCsound turns your iPad and iPhone into a complete Csound workstation that lives inside your favourite music apps.
