Lets have totally customizable stumming by milliseconds. And more Arp patterns. I think the Kurzweil k2600 had over 700 patterns. And then let each chord have its own settings for strums and Arp.
We built the strumming engine as completely customizable. At the moment we allow only for 3 different types of strum, but the plan is to create more and even maybe, as you said, leave customization up to the user.
We need more time to make it easily usable and build a nice control interface around it.
About the arp, we will add some patterns with the upcoming update.
We had to make choices and couldn’t add everything to Scaler 1.5, but the development is continuing
