Test 5: Selecting the “DreamRodes” voice by direct numeric entry
When the DreamRodes is selected in Voice display mode, the upper left portion of the screen displays “VOICE-I D05(53)”, which translates to “Voice Mode, Internal Bank – D, patch number 53″. Using this knowledge, we can jump immediately to the DreamRodes any time we have the Internal memory bank selected.
Buttons:
“5″ – [5]
“3″ – [3]
“Enter” – [E]
Notation:
[5 \ /]*1 / 0.5s [3 \ /]*1 / 0.5s [E \ /]*1 / 0.5s = 3 operations / 1.5s
Quality:
If you know the number of the voice you’re selecting, this is the way to go. It requires the least number of operations in the least amount of time. The downside is that it requires what Donald Norman refers to as “knowledge in your head” of a system. You must already know the voice number corresponding to DreamRodes.
Notes:
I assigned short durations to these button presses as they are located close to one another.
