The Mono button allows you to toggle between recording a single note at a time or multiple notes simultaneously (chords). Sequential (monophonic) recording can often be better when recording drums or monophonic instruments. Use the drop down menu next to the value box to manually quantize a range within the current pattern after recording. The "Q" button enables or disables live quantization, while the value box to the right specifies the quantization value in lines. This is done with the quantize controls in the Pattern Editor control bar: If you do not want to precisely record your notes, you can let Renoise quantize them either in real-time or after recording something. The note delay column allows you to delay notes with a precision of 1/256th of a line. When recording notes "live", by default they will be recorded with the highest possible precision using the Note Delay sub-column in the Pattern Editor. You can also adjust the amount of bars the count-in lasts here.
