TouchOSC iPad Template for the Rhodes Chroma

Rhodes Chroma TouchOSC Editor

YouTube via matrixsynth | November 21, 2010 |


"The Chroma has a slightly, conceptually different architecture than most analog poly synths. On most you have two oscillators that are routed through a filter with shared modulation sources such as envelopes and LFOs. On the Chroma, each of two oscillators, Wave A and Wave B have corresponding filters, Filter A and Filter B, LFOs called Sweep A and B, and so on. The routing is not fixed and is very flexible, meaning you can use modulation sources on B with A and vice versa. There is too much to go into here, so check out the excellent Rhodes Chroma site for more: http://rhodeschroma.com/.

As for this video, the Chroma starts with an initialized patch which only has one "Wave/Patch" active. In the beginning I adjust the pitch for Wave A which is active. I then show Wave B is inactive by attempting to adjust its pitch which does nothing. I then enable Wave B followed by applying various modulations to filter and pitch for both. This video is not a performance and is only meant to show a little of what the Rhodes Chroma TouchOSC editor is capable of." See the screens above for reference. Below is a shot of the iPad on top of the Chroma.

Update: see this post for an editor that does not require The Missing Link.

For The Missing Link you can find templates here. One is for TouchOSC and one is for OSCulator.

For those new to TouchOSC and OSCulator, TouchOSC provides a JazzMutant Lemur-like control interface that is completely configurable. You can read more about it on hexler.net here. TouchOSC only transmits Open Sound Control messages. To translate these messages to MIDI CC you need something like OSCulator.

The two templates in the share above are for TouchOSC and OSCulator. For TouchOSC you just need to drop the mapping in the templates folder and sync to your iPad. You can then select the mapping. For OSCulator, you just need to open the template, click on the Settings icon and set it to use whatever MIDI out you plan to hook into your Chroma. Note you do need the CC+ upgrade on your Chroma with MIDI set for Expanded Mode MCM.

The screens show all editable parameters of the Rhodes Chroma. If you have a Chroma, you owe it to yourself to check out the Rhodes Chroma website and join the email list.

  2. You can still check it out. The Missing Link is coming soon and won't require a Mac or PC. You can go direct iPad to your Chroma with it. See this post on how to order one. See the label for more posts.
