Oscillator is a simple and rough audio generator application which has the following functions. You can use it as a test tone and play it as a strange musical instrument. - Four waveforms. (i.e. sine wave, square wave, saw wave and white noise.) - Exponential Frequency control using the slider. - Frequency numeric input using the software keyboard. - Equal distance panning control using the slider. - dB style amplitude control using the slider. - Sound output on/off button. - All sliders and buttons are multi-touch controlled. Please note the limitations below before you purchase/use this application. - The frequency control is not effective with the white noise oscillator. - The panning control is not effective with an iPhone internal speaker because it is monophonic. Use headphones or stereo speakers. - The audio output might be interrupted on a keyboard input, a view change and so on. - The accuracy of the audio output is not very high but it is reasonable.

TMA OS is the first app built specifically to help independent music artists figure out who they are and build a brand that actually connects. Whether you've been in the music industry for years or thinking about stepping into the industry, this is the only guidance you will need. Created by Don Darkoe, a drum and bass artist still active in the scene, alongside a community of over 1000 DJs and Producers who were tired of the same recycled advice that doesn't work anymore. The missing piece no one talks about is your identity. ------ WHY THIS EXISTS - The music industry has changed. - Talent isn't enough. - Releasing songs isn't enough. - The artists winning right now have one thing figured out that most don't. - They know exactly who they are, their archetype. - And everything they put out reinforces it. Most artists skip this step entirely... They post random content, change their style every few months, and wonder why nobody remembers them. TMA OS fixes that by giving you INDI. A personal AI mentor that guides you through a brand discovery journey built on real psychology, not surface level tips. ------ WHAT MAKES THIS DIFFERENT INDI is a voice in your ear. Literally. A guide that lives in your pocket... You'll listen to daily personalised voice episodes that break down your unique archetype combination. Based on Carl Jung's 12 psychological archetypes, INDI matches you with one of 132 primary and secondary combinations. The same framework behind every artist, brand, and character that's ever felt magnetic. You won't get a quiz that tells you you're a "creative soul" and leaves you with nothing. You get a full journey that rewires how you see yourself and your career. ------ WHAT YOU EXPERIENCE IN THE APP STEP 1: You take an assessment. Quick, honest questions about how you create, communicate, and move through the world. STEP 2: Then INDI reveals your archetype combo and walks you through 9 voice episodes. Each one covers a different layer: Your strengths. Your shadow side. How you naturally show up. Where you self-sabotage. What makes people trust you before they've even heard your music. STEP 3: After each episode, you reflect. The app captures your thoughts and INDI remembers them. She builds context on you over time so the guidance gets sharper. STEP 4: Repeat and follow your Daily Insights. Once you finish your Brand DNA journey, every morning INDI drops a short voice memo tailored to your archetype, your goals, and where you're at. Real frameworks from brand psychology, marketing, and creative strategy. ------ HOW THIS IMPROVES YOUR CAREER You stop second-guessing every post, every release, every decision. You finally have language for what makes you different and why people should care. Your content becomes consistent because you know who you're being. You stop copying other artists and start building something that actually feels like you. You move faster because you're not stuck in your head wondering if you're on the right path. ------ THE MODERN ARTIST MINDSET TMA stands for The Modern Artist. A mindset for artists who adapt instead of complain. Who take full ownership of their career instead of waiting for a label to save them. Who understand that attention is the new currency and branding is the leverage. This app is built for that artist. If you're still hoping good music alone will get you noticed, this probably isn't for you. But if you're ready to take your career seriously and want a mentor who actually understands how artists are wired, INDI's waiting. ------ WHAT'S INCLUDED Free: Archetype assessment plus your first 4 episodes. TMA VIP: Full 9-episode Brand DNA journey, daily personalised insights, and everything INDI builds for you going forward. Built by an artist. For artists. No gatekeepers. No label politics. Just clarity. Welcome to TMA OS. Terms of Use: https://tmaos.com/terms
