major sketch pad

major sketch pad free chorder | step-sequencer by af Kreativt Darhus

major sketch pad is a free chorder and step sequencer VST plugin developed by af Kreativt Darhus. Compatible OS(s): Windows.

major sketch pad is ideal for musicians with writer’s block or knob twiddlers who easily get distracted by fine tuning soundscapes and ending up not getting any music done. No, this is not some pseudo-random-crap, you are in control of your music all the time when using the sketch pad. This is an arrangement utility rather than a music production tool.

major sketch pad is basically a step-sequencer combined with a chorder. Each time it gets triggered by a MIDI note the step-sequencer steps forward and each step can contain a new, different chord. The chords aren’t locked to a predefined pitch. This means that you can try out chord combinations and see how your melodies will sound with different chords applied to them, or just jam away.

The main idea behind the sketch pad is to make it easier for people who are having a hard time coming up with songs to at least get a “rough” arrangement sketch that they can continue to work with. It is, after all, often the beginning of a song that is the hard part to come up with.

KTDrumTrigger free audio-to-midi by Smart Electronix

KTDrumTrigger is a free audio to midi VST plugin developed by Smart Electronix. Compatible OS(s): Windows, macOS.

By Koen Tanghe @ Smart Electronix.

KTDrumTrigger is a VST plugin with a custom editor that triggers MIDI notes based on the sound level of the incoming audio stream in different frequency bands. It allows you to “detect” occurrences of percussive sounds in an audio stream and send out a MIDI event whenever that happens.

Incoming (mono) audio is split up into different frequency bands using three tweakable filters. The signal in each of these bands is sent through an envelope follower. When the envelope reaches a specified threshold level, a MIDI note on message is generated. The trigger module has some built-in hysteresis and minimum inter onset time settings to avoid fast successive triggers due to noise on the envelope curves. Visual feedback of the filter and trigger settings is available.
