Borsta is a virtual drum and percussion instrument. What sets Borsta apart from similar instruments is that its audio engine supports a brushing feature that can simulate strokes and brushes with continuous changes in intensity. This makes it possible to create an endless number of very lifelike brushing phrases and rhythms, something that can’t be easily achieved with ordinary sample-based instruments.

The internal sequencer allows you to determine exactly when to start a stroke, how the stroke’s pressure/speed should evolve over time and when to end it. On top of that, each instrument offers a couple of multi-sampled one-shots with advanced choking capabilities.

The initial version of Borsta comes with 18 different instruments, but each instance of the plug-in emulates one single drum instrument at a time. That means the sequences can only be played one at a time. However, switching between sequences can be done seamlessly via MIDI, and additional one-shot samples can be triggered using an ordinary MIDI track.

Each instrument is structured and MIDI-mapped in a uniform way, which makes it possible to use the same sequence on any instrument. For instance, a traditional swing pattern will sound musically correct no matter whether you choose a Frame Drum, Tambourine or Snare Drum - it will just sound like the musician changed instruments.

Each instrument is based on more than 400 high-quality samples, recorded for playing with different velocities and round robins.

Brilliant Design, Excellent Quality

The engine and sequencer are very clever, versatile, and effective. The samples range for standard brushed snare to all kinds of objects that provide extraordinarily musical results. It also includes an exciting and delightful library of grooves that you can just listen to and jam along with. These apps from Klevgrand are so good!!

I'd love it if they could add some "endings" to their sequence library. Nothing fancy, not like a trashcan, but just those rolls or flourishes that percussionists do when there's a fermata at the end of a song.

Absolute fantastic drum app

This is truly one of a kind, organic and unique in both sound and features. It has completely reinvigorate my love for iPad music making. I highly highly recommend this one.

Two things I’d love to see are randomization features for the sequence and the ability to have a different amount of steps on the brush and hits for polymeter beats.
