Audio Delay

• The audio output might sound a bit delayed (by up to 23ms). This is due to the improved chord recognition, as the plug-in waits a moment in case more notes arrive, so it doesn't play a wrong chord.
• The following settings can reduce the delay:

1. Set Humanize to Tight

2. Set the Player Sync to Song Position:

3. As a compensation, film composers with high-end sample libraries use a negative MIDI-delay for the track. You can do this with IRON 2 as well, if you want it to play tighter to super-tight. How to exactly do that differs from DAW to DAW.

4. Try placing the MIDI notes a bit too early. Make sure they don't overlap though.

Playing Legato & Quantization

• If notes overlap, the plugin engine will recognize that and try to play an interval or a chord. So playing legato or having not quantized MIDI data can lead to unwanted results.
• Make sure to always have a small gap between the notes that don't belong together!

Studio One

• IRON 2 supports the Presonus Studio One Integration (Follow Chord Feature and Sound Variations; VST only). This feature might interfere with the regular way of using MIDI notes in the piano roll (highlighted red).
• If you don't wanna use Sound Variations, simply go to the Sound Variation settings and select "Use Activation Sequence".
  
  
  
• Also the Follow Chords feature only works in Play Mode: Chord
  
  
• After reopening a saved session, the Follow button needs to get switched off and on to reactivate the feature.
  

Pro Tools

• Initial preset might not get loaded.
• In order to play back dragged MIDI phrases you need to switch to Instrument Mode.
  

DAW Crash

• Under certain rare circumstances playing sus4 or sus2 chords may result in a DAW crash.
  

Force

• Using the Force control sometimes might cause a slapback echo-effect.
  
  

MIDI Drag'n'Drop

• Playing dragged MIDI Phrases might cause switching of phrases in Player Mode.
