MIDI Simplified 1.6

Control MIDI devices with 32/64bit VCL/FMX components for Delphi 10 supporting native Windows and macOS. Support for iOS (Beta) and Android (output only). Packages in beta for C++ Builder and Lazarus for easy build and install. MIDI (Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing and recording music (Wikipedia). This package provides 3rd generation of components to simplify communication with musical instruments, developed with high-performance in mind. The package also comes with a high-priority system timer and a MIDI clock component. You can register threaded observers, giving you MIDI events in real-time with timing, or non-threaded to respond in a UI environment.

CalcuFp

New version: CalcuFP program is a calculator software (beta version), has a wide range of mathematical functions, specific functions for different subjects (ex.- IPv4 functions), Apart from being able to have on hand an wide range of functions, allows to use different numbering systems WITHOUT CHANGING MODES. We can sum operations decimal, binary and hexadecimal mixed. Example. - 25 + BIN ('111 ') + HEX (' FF ') -> this is equivalent to adding the integer 25 +7 (binary) +255 (hexadecimal) = 287. Allows use of predefined variables and constants. Creating user functions. It has a programming section through type pascal scripts (still in testing), It has a multimedia viewer to store documentation that we have on hand for our daily tasks. Aside calculators comes with color coded for resistors, inductors and capacitors. Support matrix calculation. Solving systems of n equations. Periodic table of elements. QR code generator Create new User functions with pascal script.

SPINA

SPINA is software for the rapid, reliable and accurate determination of constant structure parameters of endocrine feedback control systems. It is a class of static function tests that require nothing more than steady-state concentrations of hormones or metabolites obtained in vivo. The first version of this cybernetic approach had been developed for the evaluation of the functional status of the thyroid gland, i.e. thyroid's secretory capacity (gain of thyroid, GT or SPINA-GT) and sum activity of peripheral deiodinases (GD or SPINA-GD). A second version has been established for insulin-glucose homeostasis. It delivers the secretory capacity of pancreatic beta cells (SPINA-GBeta), an estimate for the insulin receptor amplification (SPINA-GR) and a static disposition index as a measure for the loop gain of the feedback loop (SPINA-DI). Both implementations of SPINA have been validated in more than 50 clinical studies based on large cohorts.

Transposer

Transposer converts the chords of a text file which contains the lyrics and chords for a song into whatever key the user desires. Version 1.0 no new features, just some UI cleanup. No bugs reported since last BETA, so nothing to fix at this point. (0.56) was the first with a mechanism for creating an ignore list of words which might get transposed if they are on a line by themselves, such as, "ending". This word is typically made of characters which are valid chord characters that would otherwise be transposed. There are two editing panes in the main window. One is for the original song, and the other is for the transposed song. Earlier versions of this program were command line only (CLI), then I used QT to augment my C++ source to create a GUI. This project is now developed in Lazarus, using a collaborative approach. I (abudeveloper) and my son (iamslinger) are working together on this project.
