davedroug i have recorded drum clicks in different BPM i use audacity which is free app load your song then just copy and paste your count in to the beginning of your track and save it in what ever format and bit rate you want Audacity is a great audio track editing tool i use it all the time for levelling volumes ,graphics, speeds etc and very simple to use
I think your method of fixing this particular need is great and i also use Audacity for a lot of my quick editing needs as its a great program that works on PC and Mac , and your work around is a nice one, but i feel as though we should not have to do any of that especially people that are not that computer savy, all we are asking for is a simple visual quide to the actual start point, just like in real life band starts where a member yells out 3 4 and off you go the whole band starts , this has no relevance to the tempo or type of beat it just gives us the accurate start point.
This could be easily incorporated in to the delay start function , so when we program the delay start we are actually programing a visual prompt as well where we get quided to the start point, this would not involve much effort to create yet would give us a very easy to use count in .
As i use a delayed start already so i can position my right hand to my guitar as i hit start button a nice 3 2 1 on screan would simply give me an accurate start point, i dont need anything else, as all my lyrics are line synced and i have my ears that can hear the backing track i dont need to spend hours extra to create a click in front of all my files.
All my files are edited to be instant start for very good reason on stage as sometimes i want a very instant start i actually dont want any delay at all as i start but because of the hand positioning issue i use the delay start, i know i can use foot pedal to instantly start but sometimes i do not use the foot pedal i actually use my finger on ipad.
Smaller quick gigs i dont use any remotes.
So it would be nice to just engage this function for smaller gigs and disable it for larger gigs where i dont touch the ipad at all.
