I run the unit now in Isadora with Madmapper. I am just playing with the scaler. I would already be very helpful if the Size also had an option for spacing. Now the repetitions only got that option. If you add spacing for the pixels as well, you can manage that 48 by 16 very good. Since I make a sort of step sequencer (yes within Izzy mapper!) I like to give all the positions enough room to see the right color and intensity.
