Hi,

I'm trying to capture raw MIDI data from several old MS-DOS games (Cartooners, Commander Keen 6, and Prince of Persia) but for some reason failing. These are the step I go through when trying this:
1. Start DOSBox 0.74 using the configuration specified in the file attached to this post.
2. Press the CTRL+ALT+F8 keys. The following message appears in the console: "Preparing for raw midi capture, will start with first data."
3. Start a game and let play some music. I'm almost 100% certain all three the games I mentioned use MIDI music.
4. Press the CTRL+ALT+F8 keys again. Now the following message appears: Stopped capturing raw midi before any data arrived.
5. Quit DOSBox.

The message that appears that step 4 is odd given the fact that a game is/was playing MIDI music at the time.

My computer:
1. Motherboard: MEDIONPC MS-7728 (CPU 1)
2. Processor type and speed: Intel Core i7 2600 @ 3.40GHz - Sandy Bridge 32nm Technology
3. Amount and type of RAM: 8,00GB Dual-Channel DDR3 @ 665MHz (9-9-9-24)
4. Video board w/ RAM amount and type: SyncMaster (1600x900@60Hz) 1024MB ATI AMD Radeon HD 7450 (Elitegroup)
5. Sound board: AMD High Definition Audio Device
6. Operating system: Windows 10 Home 64-bit (English)
7. Reproducibility of problem: Always.
8. Sound mode used: ???
9. Version of emulator: DOSBox v0.74

I've already done some searching on the internet and I find a lot of rather technical stuff which appears to be unrelated to my issue. I would appreciate it if any one here could point me in the right direction.

Thanks in advance.
