"O" realtime play | I connected Yamaha MONTAGE6 and Pokemiku to my PC. Montage 6 key send MIDI data to Pokemiku immediately. Realtime play is available. I chose "O" and added reverb with external effector. The voice is monophonic. Legato play adds portamento. Modulation wheel adds vibrato. CC(Control Change)#7 and CC#11 change the loudness. Velocity is valid, too. |
Preset lyrics "Choucho" realtime play | We can choose a lyric from 5 preset lyrics. This old song about butterflies is popular for Japanese kids. I used pitch bender. |
| General MIDI #1 Acoustic Piano | We can use multi-timberal General MIDI sound source with MIDI channnel 2. This sound is GM#1 Acoustic Piano. |
"Kaeru no gasshou" realtime play | I input lyrics of "Kaeru no gasshou", songs for flogs. The song came from Germany. The German title is "Froschgesang".
I used modulation wheel for vibrato. I did ritardando. Realtime play of Vocaloid is amazing. With usual Vocaloid software, I should use PC to make vocal track first. After put the vocal into mucic sequence software project. Pokemiku is a real hardware synthesizer. |
"Kaeru no gasshou" by System Exclusive Programming | Without realtime control, System Exclusive(Sysx) data can set the lyrics. The image below is MIDI data list includes notes and Sysx datas. Red lines are Sysx. During playing note, Sysx can be sent. This program has no vibrato. |
"Kaeru no gasshou" perpetual canon with 2 Pokemikus | I put the data above to two tracks of music sequencer. After a little adjusting, I sent datas to two Pokemikus. |
Pokemiku starting sound | One more extra. You can hear "Pokemiku!". |
