Francisco Ruiz Posted January 3 Share Posted January 3 (edited) Shortly after buying a CDP-S350, I started hungering the greater control over the sound of the Privia and Casio high-end models. The factory patches are terrific, but I wanted more reverb, softer hammers, more "I don't know what" (preferably said in French). But, alas! I was poor. Then a friend gave me an old iPad mini, and Santa Claus dropped a Korg Nanokontrol2 down my chimney. Now I've got all of that nuance I was missing, plus some, courtesy of the CDP-S350 MIDI implementation. In essence, the keyboard will not only send out notes through a cable connected to its USB-B port, but also will play when MIDI messages come in through that port. And not only notes, but also all kinds of codes that tweak the way the sound is produced. I can use the knobs and sliders of my Nanokontrol2, which is narrow enough to sit on top of the keyboard without impeding performance, to tweak reverb, attack time, chorus, everything, in real time. Here's what you need: 1. USB-B to USB-A cable, as for a printer (likely you have that already). 2. USB hub (USB2 is enough because of the low bandwidth) with two or more ports. 3. iPad or iPhone. It can be very old because of the low bandwidth required. I think an Android device might work too, but I have not bothered to find the software that will do the magic. 4. "camera connection kit" to convert USB to the Lightning port of the iPad (Android will need a different adaptor). 5. App that will echo MIDI back to the input. I use MIDIflow, which costs a few bucks, but the free MIDI wrench works too. No idea what the app would be on Android. 6. MIDI control surface full of knobs and sliders, plus a few buttons. I got a Korg Nanokontrol2, but there's also a cheap Chinese one that might work just as well. 7. Obviously, a Casio keyboard with MIDI capability. Mine is a CDP-S350. And here's what you do: 1. Program into the control surface the CC numbers for the features you want to control on your keyboard, on channel 1, associating hardware components (knobs, sliders, and buttons) to CC numbers. I am attaching the list, taken from the CDP-S350 MIDI implementation chart, at the end of this post. The Nanokontrol2 has a software that allows you to make any of its knobs etc. send CC messages for any number and any MIDI channel. Channel 1 is the main keyboard patch, without layering or split. You may want to put stickers next to each control, to remind yourself of what it does. A list is at the end of this post. 2. Mount it on your keyboard (I found the area left of the power button to work best for me, with some adhesive velcro), and attach a USB cable to it. Also attach a USB cable to the keyboard. 3. Connect both USB cables to the USB hub, and that to the iPad with the camera connection kit in-between. 4. Turn on the iPad and open the app. MIDIflow works by mapping an input to an output, so I run two paths, both on channel 1: one feeding the MIDI IN from the Casio keyboard to out to the same keyboard, the other feeding the MIDI from the Nanokontrol2 out to the Casio keyboard. 5. Go to the menu on the keyboard, MIDI section, and turn Local OFF. This will cause the sound to be produced only as a result of the MIDI messages coming in through the cable, and not directly from the keys. I found the delay caused by this process to be unnoticeable. And that's it! Now your keyboard should be responsive to the knobs and sliders on the control surface. Your reverb can get much greater, as well as your chorus, and everything. You can make the attack so slow that a piano will sound like a violin. A lot of release time will cause notes to blend, pretty much like having a lot of internal resonance. Here are a few pictures of my setup, and below a table with the CC numbers that work on the CDP-S350 And here are the CC numbers: CC number Action range 1 modulation 0-127 5 portamento time 0-127 7 volume 0-127 10 pan 0-127 11 expression 0-127 64 hold off/on 0,127 for a button 65 portamento off/on 0,127 for a button 66 sostenuto off/on 0,127 for a button 67 soft pedal off/on 0,127 for a button 68 legato off/on 0,127 for a button 71 filter resonance 0-127 72 release time 0-127 73 attack time 0-127 74 filtr cutoff 0-127 76 vibrato rate 0-127 77 vibrato depth 0-127 78 vibrato delay 0-127 84 portamento control 0-127 91 reverb send 0-127 93 chorus send 0-127 94 delay send 0-127 120 all sound off 0 for a button 123 all notes off 0 for a button 126 mono mode 0 for a button 127 poly mode 1-127 for a button Edited January 4 by Francisco Ruiz 1 1 Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted January 3 Share Posted January 3 Now that's thinking. Way to go! Awesome setup. Quote Link to comment Share on other sites More sharing options...
