Tactile buttons
General purpose tactile button can be used as NOTE or channel shift upto / downto 3. Every time channel changed, the channel shift status LED blinks.

TRS Selector
TRS selector is added lately to support both type A and B. Because of the limit space, TRS 3.5mm port is used. You might need to use TRS to DIN adapter but there are two types (A and B). Old version only supports type A but now, you can switch them. Very convenient!
