Looking to generate multi riffs but it seems they only generate part of the song and not till the end . am I doing something wrong ?.

Multi riff tracks at the bottom.

It should generate as many bars as you want, but it doesn't generate the 2 or 4 bar ending bars.

If your song has multiple choruses and you want it to generate multi-riffs for the complete song (all choruses), you could:
1. Highlight from bar 1 to the total number of bars in your song. If your song has three choruses of 4 bars plus the ending, highlight from bar 1-12.
2. Go to 'Custom... | Riffs of Selected Region'.

Good stuff Thanks for the reply.
