I'm not sure how to answer that. Whether you use the EDP as the master or the slave is really just a practical decision, depending on the application and what you are using it with. what do you want to do with it? >Can you describe how the EDP establishes tempo ... Is it via some sort >of tap tempo or is it based on the length of the loop? in general it is based on the length of the loop and the setting of the parameter called 8ths/cycle, which determines how many 8th notes the basic loop length (or cycle) is equal to. It is "tap tempo" to the extent that you tap the beginning and end of the loop, but not really the same as what is called "tap tempo" on other devices. When the Echoplex is the sync master, this is really simple in use. You just record your loop as you play, and when you end the loop it begins sending clock and repeating your loop. Downstream sequencers, drum machines, or other tempo based effects immediately start up in time with you as you finish. So you don't need to know what the tempo is before you play, which can be nice. Now, If you have sync coming in from another device, either by midi clock, BeatSync, or BrotherSync, the tempo is set by that sync signal and displayed on the screen. Then when you record, your loop lengths will match that tempo. Also, there is a new feature in LoopIV called Tempo Select, where you can set the tempo in advance. You set it in BPM and the Echoplex determines the loop length for you. When you record, the loop length will automatically go the predetermined amount. In fact, it will neatly do multiples of that length in real-time, so if you set it to 120BPM clock coming in and 8th/cycle set to 8, the display will show that the cycle length will be 2.0 seconds. Then when you record, if you let it go longer than 2 seconds you will see the Multiple counter going up, effectively counting the bars for you. You can then stop recording anytime you like and the cycle will be neatly rounded off for you. Also with Tempo Select, the Echoplex can start sending midi clock before you record the loop, so you can trigger downstream sequencers in time with your loop before you record it, while still having the EDP as the clock master. > I also read >somewhere that the EDP can even be used to establish tempo as master >sync without even recording anything or actually looping. How is this >done? that's the tempo select I just mentioned.
