seems very stable compared to a lot of similar long delay effects. Fairly good GUI...... considering a lot of music plug-ins have dreadful ones. Using this with Logic, it would be nice to see that this was synced to the track's BPM..... I've a feeling it might not be which makes it less useful to me just for long delayed repeats. So, although I'm currently bowled over by the tape effects it would depend on how often I actually needed them as to whether I would buy it.
