Version 1.9 is released!

VADrumSM

Virtual Analog Drum Machine

VADrumSM is a standalone mobile drum machine featuring a virtual analog drum synthesizer and a step sequencer. The virtual analog drum synthesizer supports AUv3 Audio Unit extensions, which allows users to use the drum synthesizer inside of AUv3 hosts, such as Apple’s GarageBand®. The step sequencer supports Ableton Link which allows users to synchronize the sequencer to Link-enabled apps and devices.

Drum Synthesizer

The drum synthesizer is inspired by the iconic analog drum machines of the 1980’s and features 21 drum voices. Sounds of the each drum voices are synthesized in real time by using component level modeling. Unlike sample playback, each hit sounds subtly different just like the sound of the analog drum machine.

Step Sequencer

The step sequencer is designed to be intuitive and easy to program. It is a 16 step sequencer with 3 accent level for the each step. Double hit mode allows to program two 32nd notes instead of the one 16th note. There are 4 patterns and can be chained to create 4 bar loop. Swing has 6 variations and it can be applied in real time.

Parameter Automation

All XY parameters (tone, level and pitch) and voice switches can be automated, that gives a whole new sonic possibility. Recorded automation can be overridden or overdubbed.

All parameters can be edited in Automation Editor.

Pads

Multi purpose pads can be used as XY controllers, XY controllers with trigger or drum pads. When using the pads as XY controllers with trigger, you can trigger drum sounds with different parameters in each hit and the triggered notes with the parameters can be recorded. 

Mixer

17 output buses, mix and 16 instrument outputs can be routed to main output and 4 aux mixers. AUv3 effects can be inserted to each channels. Sum of the 4 aux mixer outputs can be routed to Audiobus’s second output port.
