I am playing on a viola softly on c e and g across 4 octaves without applying eq recorded with a dynamic microphone in my room with a computer using my hands to play the instrument.
A synthetic bass multisample. I created it using the virsyn cube additive synthesizer (vsti). I applied some eq using the sonalksis sv-517 equalizer plugin. The sound was compressed by the sonalksis sv-315 and nomad factory blue tubes cp2s compressor plugins. All great quality plugs. The sound is a nice but rather static emulation of a bass guitar. Use your sampler's velocity and pitch bending options to bring this multisample to life. All samples in a 24 bit, 44. 1 khz resolution. Loop points were added for sustained notes.
Synth strings through home-made combfilter (32 reason peq-2 two band parametric eqs in series). Samples originally made with reason & logic softsynths. 37 samples, in minor 3rds, looped in redmatica keymap's penrose loop algorithm, and squeezed into 16 mb!.
A quick multisample snare hit i did with pro tools 10. I didn't add any reverb so y'all could choose one that fits your project, but it's full and punchy. Sum to mono if you don't like the subtle panning i added. Enjoy!.
