![]() ![]() The other issue to consider is that the outputs on older MOTU interfaces typically max out at around ±4V. However, if you already have an old MOTU that has ADAT ports (or can get one super cheap), you could get this Class Compliant ADAT interface and use the MOTU as a standalone ADAT to analog converter. The only issue with old MOTU interfaces is that they aren't Class Compliant, so they won't work with iOS devices. Otherwise, the ES-8 is great, or just stay all-MIDI and get the Shuttle Control or FH-2. You can find old used MOTUs for less than $100 on eBay, though do your research to see if it works with your version of iOS. That app has many CV and MIDI modules, and is very easy to use. Just set the range to around the lowest, using the red circular bar, after double-tapping the red CV knob. in zMors Modular, the LFO is in the audio oscillator. Most of the output jacks on the MOTUs are not DC-coupled, which means they don't block super-low frequencies, which is where LFOs live. If you have an old MOTU audio interface laying around, you can use it to sent control voltage, instead of MIDI, to your Eurorack. On the CV side you could try slew limiting or low pass filtering of the output from the 2hp and see if that said: 2hp state that their CV outputs have 12bit resolution, so I guess it's possible for them to make a firmware update that has a mode with more smoothing. Perhaps Mozaic will allow 14 bit messages?īeyond that, as others have mentioned, more sophisticated MIDI-CV converters have smoothing functions to alleviate this zippering. Quantum Sequencer does, MIDI Designer Pro 2 does, not sure what else. The trick is finding iOS apps that support it. Directly with the pitch bend (because we're very sensitive to pitch fluctuations, less so to level), but also with CCs by pairing CC 0-31 with 32 - 63 (CC 0 has the most significant bit, CC32 the least significant bit of the pair CC1 and CC33 etc.). MIDI does provide for 14 bit control messages (16,384 steps). ![]() The issue you're encountering is not unique to iOS, desktop systems are just as problematic with MIDI and modular communications without specialist solutions. MIDI continuous controllers are confined to 128 steps by definition. The clock dividers, gates and triggers are ace so no complaints about that. Is there any other way to get a smooth LFO out of this work flow besides the "pitch bend trick"? ![]()
