Free manila envelope software for pda

PiezoPower! is a fun little noise making app for your palm.
You can draw out amplitude envelopes and frequency curves to make your own loops and songs.
With IR capabilties, you can trigger sounds on other palms, or have call and response.
System requirements:
- Palm OS v3.0

MSX emulator for the S60 platform. MSX is an 8-bit home computer that first saw light in 1983. With this emulator you can play hundreds of games available in the web for the MSX platform. Emulation core is originally based on an adapted version of the fMSX/Unix version 2.7 source code.
Although recent versions of the emulation core still resemble the fMSX/Unix logically almost no part of the original fMSX/Unix code is left in fMSX/S60. I have decided to keep the emulator name as fMSX still to honour the roots of the emulation code and the efforts of the fMSX/Unix author. Critical sections in fMSX/S60 have been written directly in ARM assembly language to gain speed.
Main features:
- Emulates MSX1, MSX2 and MSX2+ machines.
- AY8910 (PSG), SCC, SCC+ and YM2413 (OPLL, MSX-Music) sound chips emulated.
- Supports ROM cartridge (.rom), disk (.dsk) and tape (.cas) images in uncompressed, gzip compressed (.gz), zip compressed (.zip) and lharc compressed (.lzh) format (zip and lzh format support is in the "b" and "d" variants only). Compressed disk and tape images are treated as read-only media in the emulator (any saved data on compressed media will be lost when the emulator exits).
- Four supported display rendering modes with 90 degrees rotation possibility (cw/ccw):
- raw unzoomed (only a part of the MSX display is visible in 176x208 display)
- fast fit (every nth pixel is discarded in 176x208 display or doubled in bigger displays)
- smart fit (same as fast but with a lone-pixel-detection, only available in 176x208 display)
- resample fit (calculates the average of neighbouring pixels for each rendered pixel, only available in 176x208 display).
- Fully user configurable keyboard and joystick mappings.
- Emulation can be paused and the machine state can be saved and loaded.
Enhancements:
- AY8910 (PSG) envelope frequency emulation bug fix
- 64Hz/48Hz/32Hz video refresh emulation option
System requirements:
- Series 60 1st Edition devices.
- 176x208 resolution display.
- 12bit color depth (4,096 colors) or 16bit color depth (65,536 colors).
- 8kHz 16bit PCM audio streaming capability for sound emulation. The sound emulation can be disabled if the device does not support this audio format.
