The minor 7th (min7) version of the Strat chord instruments. Minor 7 is like a jazzy version of standard minor chord. Full octave+, three strum speeds, see the descriptions of earlier instruments on the series for info.
This one has a whole bunch of note-off string/finger squeak and string muting noises that trigger randomly, delete them f if you don't like them.
Dominant 7 and maybe major 7 to follow, others too. Cheers.
Edit: I've added a quick example, you can hear most of the chords and strumming rates, it's part of the rhythm guitar track from a song I did with these. Shows that a little compression, some tube clarification, distortion and reverb can make these sound pretty good, eh? What I actually used (DSP in order): Renoise's bus compressor, Studio Devil's Virtual Tube Preamp (awesome piece of software), Boogex's "Picking Crunch" preset with its cab and reverb turned off (so only the amp), Renoise's cab sim with the "Boro Jazz" preset, bass and high freq attenuated, Renoise's mpReverb "Cathedral" setting with the wet set to 20%.
Note, you will need to EQ and compress these at a minimum to use them well – they're all raw direct input samples, so the (sometimes pretty bad) harmonics and such are still there. Treat them as what they are – raw input requiring some processing! Thanks, cheers.
