Cascadr experiments with the idea of playing a sequence of notes and a number of speeds – simultaneously. Rather than the sequences being played in time with each other (for example, 30bpm, 60bpm, 120bpm) they are played at intervals of 1bpm – which generates an interesting cascading effect.
There are eight notes in this sequence, and each note’s pitch can be chosen over a range of 2 octaves (on a chromatic scale) starting from A4 (or 440Hz). It’s also possible to alter the volume of each note, so emphasis can be placed on specific notes. Simply touch the column that represents the value you wish to change and drag up or down. When you change a note or note volume, the change will be heard straight away.
Perhaps most importantly, you can choose the speed of the sequences. As the idea of this application is to play sequences with this cascading effect, you can only choose the speed of the first sequence. So, if you choose a speed of 10bpm, the next sequence will be played at 11bpm, the next at 12bpm and so on.
Along with functions for starting and stopping the sequence, there is a ‘re-sync’ function that allows you to restart the sequence from the beginning, meaning that all of the sequences will be put back in sync again.
While there may be some ‘shock-horror’ at the lack of syncopation, Cascadr can produce some really ambient melodies and rhythms – along with some interesting chords as the sequences slide in and out of time. Just set your sequence, speed, play and listen.
I’ve got plans to add more features for customising the sequence further, and providing the ability to choose different sounds so stick around!
MIDI out via Wifi & Apple Camera Connection Kit. MIDI sends note on and note off messages, as well as velocities for each note based on the volume you’ve chosen for each note on the app.
NOTE: When MIDI out is enabled, the local sound on the iPad will not play. It’s inevitable that some latency will occur either over Wifi or on the remote sequencer. This would mean the sound from the iPad would be perceived to be out of time.
