5.1 SD CARD
The SD card contains Tonverk data, where Projects, Presets, Instruments, Samples, and global settings
are stored. The amount of data you can store on the SD card depends on the size of the SD card. Tonverk
comes with a 64 GB SD card. The recommended minimum card size is 2 GB, and it must be formatted in
exFAT format.  For more information, please see “6.11 SAMPLE BROWSER” on page 25.
5.2 DATA STRUCTURE
5.2.1 PROJECT
A project contains 128 patterns. The project also stores general settings and states. The currently loaded
project becomes the active working state of Tonverk. From here, it is possible to edit the patterns and
presets of the project. Every time Tonverk is switched on, it boots to the active working state, the active
project. Projects are saved, loaded, and managed in the FILE menu. For more information, please see “9.1
THE FILE MENU” on page 33.
5.2.2 SONGS
A song is an arrangement of patterns set up to play in sequence. Each row in the SONG mode arrange­
ment can have separate settings for pattern, row repeat, row length, and tempo. A song can be up to
99 rows in length, and each project can contain up to 16 songs. For more information, please see “10.11
SONG MODE” on page 47.
5.2.3 PATTERNS
The patterns are the primary data container for Tonverk. Sixteen patterns are available for each of the
eight banks, resulting in 128 patterns for each project. A pattern contains up to 12 presets (one for each
audio or MIDI track), plus sequencer data like trigs and parameter locks. It also includes the settings on
the TRIG page, as well as BPM, length, swing, and time signature settings. For more information, please
see “10. THE SEQUENCER” on page 38.
5.2.4 SAMPLES
Tonverk can load and play WAV and AIFF audio files (samples) with 16/24/32-bit depth (floating and fixed
point) as well as M4A, CAF and FLAC files. The preferred sample rate for loaded files is 48 kHz (mono and
stereo interleaved). Files with other sample rates (44.1 kHz/ 88.2 kHz/96 kHz) can also be loaded, but they
will gracefully degrade in quality when played back. You can load a sample of up to 45 minutes on a track.
The minimum sample size is 96 samples. Samples are stored on the SD card, and the size and number of
those samples are limited only by the available free space on the SD card. For more information, please
see “9. PATTERNS, PRESETS, AND INSTRUMENTS” on page 33.
All samples that are played on a track in Tonverk are played back with an attenuation (low­
ering of volume) of -22dB to maintain headroom in the device. The sample files themselves
are unaffected.
5.2.5 WAVETABLES
A wavetable is an audio file that contains a number of waveform waves. Tonverk supports up to 64
waves per wavetable and interpolates smoothly between them. Each wave in the wavetable must have
a power-of-two size (in samples): 64, 128, 256, 512, 1024, 2048, or 4096. If no wave size is specified in
