Audio Units, CoreMidi and Popovers

[minimalmonster]

Hey guys,

Recently downloaded the trail version of LiveCode 5 and I gotta say, it's great. 3 days work and I've already done more than weeks of work in Xcode.

Anyway before I get to deep into LiveCode and purchase it, I was wondering if it is possible to do a few things. I'm making a music creation app which in basic terms is a piano style synth with prerecorded sounds. I would like to add 3 basic effects, reverb, delay and a filter and was wondering if that's possible, would I need to use iOS externals or something else? I'm also after the ability to use core midi in iOS enabling a user to plug in an external keyboard and play with real keys. Is this something that can be done in LiveCode or iOS externals or is it not possible with using LiveCode at all?

The last thing was about Popovers on the iPad, I managed to use the iphonePick to bring up a list to pick from but is it possible to just add information to a popover that scrolls and isn't something that you need to pick from?

I'm quite new at this so I apologise if I've asked questions that are obvious to most but any info to help would be amazing!

Thanks in advance.

I can't answer your question about midi. However if you look in the Livecode bundle you will find a folder titled "Mobile Examples" the "Scroller Example" can be easily modified to do what you would like to do. Simply select the "scroller" group and chose "edit group". Delete the image object and replace it with a scrolling field. Copy your text into the field and tweak a few settings and run it in the simulator.

There is a good video mobGui put out that shows you the settings for that field. I unfortunately was not able to make MobGui;s scroller work but watching the video did help me to modify the scroller example stack with a field to fit my needs. This custom method also allows for the use of large colored fonts, list like behavior, etc so can it be used as a custom interface as an alternative to the pick wheel or away to display scrolling Rich Text Format.

PS. There are a few lines of code in the "scroller example" card script directed at the image file that you will be deleting. You will need to remove those lines of code after you delete the image file. Then test it in the simulator.

Good timing, I'm on a similar quest. Have been muscling through use of midi in a Python app I'm writing for OSX, and since I'm also learning LiveCode, decided to search for a midi capability, sice LiveCode development is faster than Python. It appears you have to link in an extension to get midi, but that has been done. Here is what I have found so far, a commercial product, just search for 'sunnYmidi'

they also have a free demo. sunnYmidi utilizes the CoreAudio framework, so there might be access to some primitive functions that could be helpful.

Please post anything else you find on this topic, I'm also interested in controlling AUs as well as full MIDI functions, including regular midi as well as sysex messages to external devices using coremidi.

Great! Thanks for the info guys, I'll have a look into those and post if I have any success.
