SpieMachine is a drum machine and sampler developed using Pure Data. Physical implementation made with a Bela micro-computer.
For now, SpieMachine gives the user the ability to play, modify, and save 8 patterns. The user has the option to cycle through 8 different kits, or patches, 4 or which are pre-set, and the other 4 are made up of user-uploaded samples.
Patterns are created in real-time using Record Mode. To start Record Mode, press and hold the Shift button, then press the Start/Stop button. The user will know they're in Record Mode when they hear the metronome begin. At this point, the user can tap-in the drum sounds for their sequence. To quict Record Mode, pres the Start/Stop button.
To select a different pattern, hold Shift and Menu at the same time, then press one of the 8 Sample buttons.
SpieMachine comes with 4 defauls kits; a Roland 707, 505, 808, and 909, loaded into slots 1 through 4 respectively. Users can add their own samples by adding a set of samples to samples directory in the build-in storage/ micro SD card in the unit. Samples must follow a specific naming convention in order to be read by the device: [kit number][instrument name].wav. Examples for kit 4 would be: 4Kick.wav, 4Snare.wav, 4CHat.wav, etc. The instrument names are the same for each kit: Kick, Snare, CHat, OHat, Tom1, Tom2, Perc1, Perc2.
