i2m with vocals??

Post by rdebs812 »

can this piece turn vocal ideas/harmonies into midis? like if i have a quick melody in my head that i would later like to find a synth for, would i be able to just plug a mic into it, sing and get the midi? and if not... could i achieve this if the vocals where pitch corrected first so that they are basically in true key? or is this piece just really not for any type of vocals at all? i would really appreciate any answers on this because i am very interested in this piece for specific purposes

Yes, it will work with vocals.

To capture exact notes, you can enable CHROMATIC mode so it will "snap" to the nearest note. If you want to lock to a musical scale you can now do this too (with our latest firmware update) so then you can never be out of tune! So no need to perform any pitch-correction beforehand.

I'm having trouble converting Vocals. My primary reason for purchasing was to use for converting vocal melodies to midi. I've tried it with guitar and there is a smooth conversion, but when I sing into a mic, I am getting pretty unusable midi information. There are a lot of extra notes and the melodies are unrecognizable when played back as a midi instrument. What is the best way to set up vocals? I have the software set up for vocals, ive tried legato on/off and ive tried Pitchbend/Chromatic and still haven't gotten results. Is there a way to have the midi information be as accurate with vocals as it is with guitar?

Thank you

This happens because the voice isn't often as controllable as a guitar, so there is lots of extra (unintentional) pitched sounds going on: breaths, plosive sounds (p, b, etc).

The first thing to do is to ensure the sound source is good. Essentially, you want to sing only vowel sounds to ensure they have as pure a pitch content as possible.

Another thing that may help, assuming that these bad notes are quieter than the others, is to enable the "velocity filter". You can do this in the "mode" page of the i2M editor. Any notes falling below a MIDI velocity you set will be ignored. This can be used to clean up "glitches" in guitar, as well as other background noises such as string noise, breath noise etc.

Yes, there is a lot of variation in pitch in the typical singing voice, even if you are a practiced vocalist! If you are having problems and want to get good optimized audio-to-MIDI tracking with vocals, you can try putting a pitch correction device in front of the Sonuus, such as one of the TC Helicon hardware boxes (many of them do pitch correction). In fact, with many of these devices you set them up to send the pitch corrected audio to the Sonuus (thus getting accurate MIDI notes), separate from the uncorrected vocal audio. Also, you can dial in the amount of correction used so you retain some of the scoops and inflections if desired.

Hardware boxes as mentioned are best for live performance because the minimize the amount of latency (delay) introduced to the MIDI output. But if you are just converting vocal to MIDI in the studio, you can even use a plug-in to do what you want, as latency is not an issue in this case. Just do some searches on pitch correction plug-ins. There are plenty on the market.

I've read in this and another thread about users having problems getting i2m to work well with vocals. The response has been, "It will work you, just need to get the pitch right and watch for plosives etc"

If I could see some proof that it can be made to work with vocals I'd buy it in a heartbeat. Sonuus has posted numerous impressive demos using instruments. If it really works with voice, please post a demo. That shoud settle the matter.

Aha! I take that as a challenge! Time permitting, I will do a video showing voice-to-MIDI, and announce it here.

I would also jump on this immediately if you can do it. Are you still planning to post something?

Yes, I still plan to do a video on this. Sorry and alas, my schedule has been full, and it takes some dedicated time to record and post a decent video. I will post a note here when I get something done...

I think ‘James’ is correct here in suggesting that the device will work perfectly fine with vocals. I am not much of a tech person when it comes to music products but I am new here and I hope to make good friends here! Thank you!
