What Borsta does
Each of the 18 instruments is based on more than 400 samples recorded at different velocities, and all of them are MIDI-mapped in the same uniform way so one sequence can be swapped between instruments. The plugin ships with 230 pre-made factory sequences and 60 Global presets covering different sound genres.
The audio engine supports continuous changes, which the developer says makes it possible to create life-like brushing phrases and patterns that traditional sample-based instruments cannot reproduce. Parallel envelope events in the sequencers let the user set exactly when each stroke starts and how it develops. Room simulation offers 9 different rooms, reverb has adjustable decay time across 6 algorithms, a timbre control adjusts harmonics, and a three-band equalizer shapes the output. A separate volume velocity curve can be set for each sound type. The plugin is available in VST2, AU and AAX formats for Windows and macOS, and a trial is offered.
Key features
- 18 brush instruments. The set includes Snare Drum 1, Snare Drum 2, Snare Drum 3 and a LOFI Snare Drum, each sampled as six multi-sampled one-shots with choking capabilities.
- Continuous brushing engine. The audio engine supports continuous changes, so brushing phrases can be shaped as gestures instead of repeated single hits.
- Envelope events in sequencers. Parallel envelope events determine exactly when each stroke starts and how the stroke develops over its length.
- Room simulation and reverb. Nine rooms can be selected for the room simulation, and the reverb offers adjustable decay time with 6 different algorithms.
- Timbre and equalizer. A timbre control adjusts the harmonics of the sound, and a three-band equalizer gives further tonal shaping.
- Velocity curves per sound type. Each sound type has its own volume velocity curve control, so dynamics can be set independently per instrument.
