Otto Audio Djaa Maasta — Free Download
A deeply sampled baritone guitar virtual instrument, tuned down to F#0, offering aggressive chugs, pinches, and special effects for extreme metal and low-tuned productions.

Purpose and Character
Djaa Maasta is a virtual instrument built around a Squier Jazzmaster Baritone guitar, specifically captured for ultra-low, heavy tones. It is tuned from C#1 standard down to F#0, reaching frequencies below typical bass instruments. The library focuses on delivering a raw, aggressive sound suitable for metal, djent, and experimental genres.
The instrument includes a bridge single-coil pickup, tracked with a Rupert Neve RNDI box and MIDAS preamps for clean, transient-preserving DI capture. Each sample was professionally de-noised to retain tonal clarity. The result is a versatile yet heavy-sounding tool for crafting low-end riffs and textures.
Key Capabilities
Djaa Maasta offers up to 16 round-robin samples and 4 velocity layers, ensuring natural variation across repeated notes. The note range spans over four octaves, from F#0 to A#4, covering low bass territory, bass VI range, and baritone pitches. The instrument uses a custom sampler framework, so no third-party engine is needed.
Articulations include sustain (down/up picking and downpick only), chugs (down/up and downpick), harmonics (tapping, pinch, vibrato, bend), tremolo picking, fast bends, and special effects. There is also a combined MAASTA articulation that mixes dead mutes, sustains, chugs, and pinch harmonics for complex patterns.
Workflow and Control
Players can switch articulations via keyswitches (A-1 to E1) or through the UACC protocol (CC32). The pitch bend wheel can be set for string bends from 1 to 12 semitones. The library features double tracking with unique samples on left and right stereo channels, maintaining mono compatibility.
The setup is optimized for quick loading and efficient hard drive usage, with a compact sample library size. This makes it practical for projects where space and loading time are concerns. All performances are triggered from a single MIDI part, reducing complex editing.
Practical Applications
This instrument is ideal for composing low-tuned riffs, palm-muted chugs, and ambient harmonics in heavier music productions. It can also serve as a unique bass source when layered or used alone in mixes that require extreme low-end. The special effects and harmonics add texture for transitions or sound design.
When planning tracks, consider using the sustain downpick-only articulation for tight, aggressive rhythm parts, and the MAASTA articulation for dynamic, momentary shifts. The pitch bend feature is useful for expressive string bends. For best results, pair it with a high-quality amp simulator or IR cabinet to shape the tone further.
