bassBox

bassBox is a sample-based bass instrument loaded with 141 presets — every single one multisampled from real hardware. Subs, stabs, reeses, warps, wide detuned monsters. If it has to move air, it's in here.

Nothing modelled, nothing emulated. Every preset was played into a Yamaha DX7II (plus expansion card), a Roland Jupiter X, a Roland JV-1080 and an Oberheim OB-6, then captured across 21 zones per patch so it actually tracks from C1 to C5 instead of falling apart two octaves up. 24-bit, 44.1kHz, stereo. Real machines, real weight.

🔊 Features

• 141 PRESETS — banked by the machine they came from. DX7II (59), Jupiter X (30), JV-1080 (28), OB-6 (24).
• 21 ZONES PER PRESET — properly multisampled, so it tracks the whole keyboard instead of stretching thin two octaves up.
• CHARACTER — ages the sound instead of distorting it. Turn it up and the bit depth drops away, the top end rolls off, and a soft saturation glues what's left back together. 
• DRIVE — the aggressive one. Shoves up to 6dB into the saturator and pulls some back out the other side, so it reads as cranked rather than just fuzzy. Gentle through the bottom half, properly mean at the top.
• FILTER — cut the top off or sweep it open.
• ECHO + TIME — tempo-synced delay when you want movement.
• WIDTH — mono to stereo. The sub stays tight and centred, the top spreads out.
• ADSR — attack, decay, sustain and release with millisecond readouts. Tight stab or long sustain, your call.
• GLIDE — mono-synth portamento. Slide into every note.
• TRANSPOSE — octave up, octave down, instantly.
• PRESET BROWSER — star your favourites and get straight back to them. Resizable UI.
• LOW CPU — big low end, small footprint.

Compatibility: VST3 / AU for Windows 10+ & macOS 10.13+. Intel and Apple Silicon. Works in any DAW that loads VST3 / AU (Ableton, Logic, FL Studio, Bitwig, Studio One, etc.).

Programmed, then sampled

Many of the sounds in bassBox were programmed from scratch on the machines themselves — oscillators, filters and envelopes dialled in by hand — and some are classic factory sounds that earned their place. Every one of them was then multisampled across 21 zones, recorded straight off the hardware. Nothing modelled, nothing emulated.
