Today I explored the Slope funcionality of the ER-102. I tried to transpose a running pattern by pressing keys on an attached keyboard (QuNexus) while staying within the choosen scale – and failed. Here’s what I did…
- I picked the MINOR scale and created a simple 3 Step Pattern: C, D#, G.
- I connected the note CV out of the keyboard to the Xmod input of the ER-102 and set the SLOPE for CV A to “1.0”.
When the ER-102 CONFIG.INI option “CV Slope Modifier behavior” was set to “post-lookup” everything worked as expected: like combining the ER-101 sequence and the keyboard notes with a Precision Adder. I could transpose the sequence for instance by an octave or single note steps. But his way I wouldn’t make sure that every final note would stay in the C minor scale.
So I set the ER-102 CONFIG.INI option “CV Slope Modifier behavior” to “pre-lookup”. Now every output note stayed within the C minor scale, but transposing by pressing keys on the keyboard didn’t work as expected at all. For instance switching octaves (pressing a C key one octave higher = switching from 0 to 1V) resulted in D, F, G#.
So what am I doing wrong here – and how could I make it work withou adding an external Quantizer? Any help would be very appreciated. Thanks!
