i2M setup for tenor or alto sax?

Postby Slimandslam » Mon Oct 15, 2018 5:33 pm

I've got my new I2M with firmware version 1.4x. I ran the software to change the settings, and I set
all four channels to "Voice/Wind". Is there anything else I need to do in order to optimize use with
a saxophone? I'm using an iPad Air 2 and Notion software.

Cheers,

Jason

For Saxophone, good microphone placement can be important. You want to make sure you don't pick up any MIDI sound, or you can get feedback (the MIDI sound is detected and generates MIDI notes for that).

You also want to keep the sound getting to the i2M as pure as possible. Here are a few other posts with some tips:

Unfortunately, those other posts were not very helpful at all.

Below are my hardware setup and an example of what's I'm seeing in the app.
The setup seems to be working as expected. I tried both Notion and Symphony Pro 5 on
the ipad and get identical results, so I think the issue is with the i2m.

So, I did individual note input of a G major scale very slowly, and that produced the first measure which
I think the app transposed. I guess there's no Midi "length" for the note? It always produced eighth notes no mater
how I played them. Then I did realtime input of a G Major scale at a slow tempo and that produced
the garbage you see later. I have the i2m set for Vocal/Wind input.

The i2M does of course include the length of the note. It sends note-on when the note-starts and note-off when it ends. I think you must have quantisation selected in the software so it's forcing all the notes to a fixed length.

It would be useful if you could send us an example of the audio recorded through the i2M. Then we can see exactly what's happening and hopefully offer more help. It's best if you can record this as a .wav so there is no lossy compression added to it, this way we can see exactly what the i2M is seeing and should be able to reproduce the MIDI conversion you are getting.

I'll send you a PM with my email address where you can send a wav file if you want to do this.

When I try to upload a WAV file, your forum software says "The extension wav is not allowed."
The extension mp3 is allowed, so I uploaded an MP3 of my G major scale on Tenor Sax. It was recorded
with an iphoneX from the same distance and in the same location that I'm doing input with i2M.

Thanks. I've sent you a PM with my email address so you can send me the wav file directly.

Hi, Everyone, I'm new to the forum. This forum is quite excited because I'm a full-time musician and I play both my Tenor and Alto sax on a daily basis and I'm a big believer in keeping my setup simple.
