Electrum - Programmable drum machine

#1 music making Android app as shown on MusicRadar.com - http://www.musicradar.com/news/tech/the-best-android-music-making-apps-in-the-world-today-276167/11

Runs on ALL android devices, even the Galaxy tablet!

Pattern-based music composition

Use samples and loops to make beats and songs.

WAV file import - Load YOUR OWN SAMPLES from SDCARD.

Look at the MENU for more options such as ability to save and load your own custom drumkits - once you've loaded the sounds you like unto the pads and adjusted them you can save the settings as a drumkit, separate from the patch itself!

RECORD samples with the microphone.

Stretch loops to fit the current project BPM.

Edit a sample's start and end point, as well as pitch.

Use other time signatures such as 3/4, 6/8, etc.

Add some swing to your beats with the SHUFFLE setting.

Sample accurate playback engine.

WAV/MIDI/Pad Export-load your song into Fruityloops!


Electrum has 8 sounds and you can program up to 32 patterns. A full sequencer allows you to string the patterns together into songs or longer beats. You can also play patterns "live", switching them as the machine is playing.

For multitouch devices, Electrum has a multitouch pad dialog as well (See Menu->Play Multitouch pads) where you can play just like an MPC by hitting the pads.

Please NOTE: The pads on the main screen are not designed to play real time. Use the multitouch pads for that. Also, any pad latency will depend on your device. For example, the Galaxy tablet is very fast, low latency, and the Motorola Droid series also had low latency. Older devices such as Hero, G1, etc, will have the worst latency.

Export your beat or track as a WAV or MIDI file.

Also check out my ReLoop music sequencer, which allows you to sequence loops just like Garageband or Sony's ACID.

Recent changes:
Fixed bugs in the WAVE loader code, should be compatible now with almost all WAV files (uncompressed of course). Was having problems with WAV's from ProTools because of extra data. I wasn't searching for the chunks properly. Recoded to search for WAV chunks now instead of hardcoded offsets.

Added code to allow pressing of the BPM display area to bring up the app's menu for easier use on Barnes and Noble tables, etc.
