The good folks at In Session Audio have released the free (for a limited time) Riff 100 library in Stylus RMX and REX formats.
Riff 100 is featuring a hundred song starters, mood setters and melodic ideas, hence its name. Riff 100 is part of In Session Audio’s BPM Flex Series, allowing any loop to be used at virtually any tempo without the use of artificial stretching.
For those who wonder, you can use the REX files in FL Studio without any problem. The advantage of a REX loop is that can dynamically match the tempo of a song, without altering the pitch of the loop, as would normally happen if the audio file was slowed down or sped up.
Below is a video showing some of the sounds.
Riff 100 library is free through Thursday, June 22nd, 2017. Download the library at In Session Audio (“add to cart” required).
