Malcolm Mugglin has continued to keep his app ChordMaps2 updated with new features! Originally released in 2016, the app got renewed interest in 2020. That cynosure continues today with an update that adds an arp!
What's new in ChordMaps2 v1.17:Added a basic arpeggiator -- (1) Set the Tempo. (2) Select 4/4 or 3/4. (3) Select the MIDI channel - "B&C" for the bass and chord channels or "ARP" for the Arpeggio Sound channel (4) Choose B for a bass note pattern, C for a chord note pattern, BC1 or BC2 for patterns that use both bass and chord notes. (5) Select a pattern (1 to 24). Enable "PLAY ARP." The next chord location touched will play as an arpeggio. (The pattern can be changed to another pattern while the arpeggio is playing.)
Also fixed a strumming situation (sliding sideways on two strings at the same time was causing notes to be triggered again).
Playing Suggestion: Strumming works well when the Chordmap region is set to play only the bass note, and the strum area is used to strum or fingerpick the chord notes. First, the left hand touches the chord location, triggering the bass note. Then the right hand answers by tapping or sliding on the strum area.
